    Windows Integrated Authentication - HOWTO

    partlycloudy

      We have been using APEX for many years with Oracle OHS. To provide Windows integrated authentication so Windows users can automatically login to the APEX app without a login screen, we used the Apache mod_ntlm module. That module is very old and NTLM is a deprecated protocol, using Kerberos is the recommended course of action. Over the last few years, Oracle REST Data Services (ORDS - formerly APEX listener) has become a stable and mature option for APEX (plus REST-ful services, XLS uploads, PDF printing and much more!) and Version 2.0 has re-added support for deploying in a Apache Tomcat container. Tomcat 8 now has built-in support for Windows authentication using the Kerberos/SPNEGO authenticator. But the configuration is not very intuitive. I spent a lot of time configuring all the pieces and finally got it working and thought it might be a good idea to share with the community.

       

      Assumptions - Change server names as needed for your environment

      1. Oracle 11.1 on Linux, server name APEX-DEV
      2. APEX 4.2.2
      3. Windows domain - company.com
      4. Kerberos Key Distribution Center (KDC) - kdc.company.com
      5. Active Directory (AD) service account for Kerberos pre-authentication - APEX_SSO
      6. Tomcat installation directory on APEX-DEV - Path in environment variable $CATALINA_HOME

       

       

      Step 1 - Install APEX (I used 4.2.2) as per the installation instructions

       

      Step 2 - Download and install ORDS as per the installation instructions. First make sure it works in standalone mode and then follow the instructions to deploy as a Tomcat container. See the reference links below for some useful links on Tomcat architecture. Tomcat itself has a very comprehensive documentation online. Be sure to rename the ords.war file to apex.war so the APEX app URLs will be /apex/f?p=...


      At this point, you should have a working APEX installation deployed as a Tomcat container webapp. It should be accessible at http://apex-dev.company.com:8080/apex


      If you go the Administration > About page and scroll down to the CGI environment variable section, you will see that the REMOTE_USER is set to APEX_PUBLIC_USER and not your current Windows login id. The goal of the rest of the configuration is to use Kerberos authentication against your Windows AD to transparently authenticate.

       

      Step 3 - Work with Windows administrator to create the service account APEX_SSO in Active Directory. See the user account configuration link below for details on what properties need to be set in AD.

       

      Step 4 - Create a Service Principal Name (SPN) for the APEX server to use for Kerberos pre-authentication.  This is done by the Windows administrator running the following commands.

       

      setspn  -A HTTP/apex-dev APEX_SSO
      setspn  -A HTTP/apex-dev.company.com APEX_SSO
      
      

       

      Step 5 - Work with the Windows administrator to create a Kerberos keytab file.

       

      ktpass /out c:\tomcat.keytab /mapuser apex_sso@company.com
                /princ HTTP/apex-dev.company.com@company.com
                /pass <password>
      
      

       

      The purpose behind these 2 steps is so Kerberos can uniquely identify the apex-dev "service". Think of it as creating a "trusted relationship" between the KDC and your APEX server.

       

      Step 6 -  Copy the tomcat.keytab file over to the $CATALINA_HOME/tomcat.keytab

       

      Step 7 - Checkpoint. Make sure that the pieces are talking to each other.

       

      /usr/kerberos/bin/kinit   -V -k -t $CATALINA_HOME/conf/tomcat.keytab   HTTP/apex-dev.company.com@company.com
      
      

       

      The output of this command should be Authenticated to Kerberos v5

       

      Step 8 - Another sanity test

       

      /usr/kerberos/bin/klist -e -k  -t  $CATALINA_HOME/conf/tomcat.keytab
      
      

       

      This should read the keytab file and list the SPNs in it, one row per encryption protocol supported.

       

      Step 9 - Open the $CATALINA_HOME/webapps/apex/WEB-INF/web.xml file and add the following snippet at the end, just before the closing web-app tag

       

      <security-constraint>
        <web-resource-collection>
          <web-resource-name>APEX</web-resource-name>
          <url-pattern>/*</url-pattern>
        </web-resource-collection>
        <auth-constraint>
           <role-name>*</role-name>
        </auth-constraint>
      </security-constraint>
      <login-config>
         <auth-method>SPNEGO</auth-method>
      </login-config>
      
      

       

       

      This is the most critical step. This instructs Tomcat to require authentication when any URL from this webapp is requested. The authentication method is SPNEGO.

       

      One caveat here - We have changed the Oracle-supplied web.xml file. The default Tomcat configuration is setup to monitor all WAR files in webapps for changes so if you modify or "touch" the apex.war file, Tomcat will automatically and silently remove the apex directory and re-create it from the WAR. Something to be aware of especially since Oracle has chosen to use the executable WAR feature to configure ORDS (e.g. java -jar ords.war <command> <option> <arguments>), an operation which modifies the WAR file. I would suggest doing the initial configuration as Oracle suggests and then making further changes by directly modifying the defaults.xml file in the ORDS configdir. I may even remove/rename the $CATALINA_HOME/webapps/apex.war file (be sure to stop Tomcat before doing this otherwise Tomcat will automatically un-deploy (i.e. delete) the apex directory!). This way, there is no danger of inadvertently re-creating the apex directory.

       

      Step 9 - APEX is "auto-deployed" using the supplied WAR file and Tomcat explodes this into a apex directory in $CATALINA_HOME. Auto-deployed web apps don't have a explicit Context element defined. Fortunately, we can override that by creating a file $CATALINA_HOME/conf/Catalina/localhost/apex.xml with the following

       

      <?xml version="1.0" encoding="UTF-8"?>
      <Context>
        <Valve className="org.apache.catalina.authenticator.SpnegoAuthenticator"
            loginConfigName="APEX"
        />
        <Realm className="org.apache.catalina.realm.JAASRealm"
               allRolesMode="authOnly"
               appName="APEX"
        />
      </Context>
      
      

       

      This is the key part of the configuration. It sets the loginConfigName on the SpnegoAuthenticator valve and the appName on the JAASRealm valve to the same value, which will be used in subsequent steps. The allRolesMode is also important because it instructs Tomcat to use this realm just for authentication and not try to do any further role-based authorization (e.g. against a LDAP or JDBC data source).

       

      Step 10 - Create a file called krb5.conf in $CATALINA_HOME with the following

       

      [libdefaults]
           default_tkt_enctypes = aes128-cts rc4-hmac des3-cbc-sha1 des-cbc-md5 des-cbc-crc
           default_tgs_enctypes = aes128-cts rc4-hmac des3-cbc-sha1 des-cbc-md5 des-cbc-crc
           permitted_enctypes   = aes128-cts rc4-hmac des3-cbc-sha1 des-cbc-md5 des-cbc-crc
           default_realm       = company.COM
      
      [realms]
           company.COM = {
              kdc = company.com
              default_domain = company.COM
      }
      
      [domain_realm]
           .company.COM  = company.COM
      
      

       

      Step 11 - Create a file called jaas.conf in $CATALINA_HOME/conf with the following

       

      APEX {
          com.sun.security.auth.module.Krb5LoginModule required
          doNotPrompt=true
          principal="<the value in the Principal column in the output of the klist command>"
          useKeyTab=true
          keyTab=<full path to tomcat.keytab file>
          storeKey=true;
      };
      
      

       

      The location of the above 2 files is defaulted. If you want to put them in a different location, you can use the JAVA_OPTS environment variable to set the location before starting Tomcat. e.g.

       

      export JAVA_OPTS="-Djava.security.auth.login.config=/path/to/jaas.conf -Djava.security.krb5.conf=/path/to/krb5.conf -Dsun.security.krb5.debug=true -Dsun.security.jgss.debug=true "
      
      

       

      The last 2 flags are to turn on debugging, very helpful when setting everything up, can be removed for Production use.

       

      For additional debugging output in $CATALINA_HOME/logs, you can edit the $CATALINA_HOME/conf/logging.properties file add the following line

       

      org.apache.catalina.realm.JAASRealm.level = FINEST

       

      Or change the logging level of org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level  from INFO to FINEST

       

      Step 11 - Restart Tomcat.

       

      Step 12 - Now when you login to APEX and go to the Administration > About page, if everything is working well, the REMOTE_USER should show your Windows username instead of APEX.

       

      This can now be used in APEX authentication schemes based on the HTTP Header.

            Thanks for this document. Sharing information is what keeps us more productive and more confident in making the right choices.

             

            If you are looking to implement SSO with Kerberos using a standard Apache, have a look here:

            In our company, we now consider Apache > ORDS (on Tomcat) > APEX as the standard configuration for each APEX installation.

                Niels - Thanks. Yup, I am aware of your solution. That was my starting point, it was very helpfu and if you recall we exchanged some emails where you helped me understand some concepts. But the more I looked at Tomcat (especially the new SPNEGO authenticator valve), I liked it. It is a very well designed, lightweight/small footprint, has great performance, scales well. Unsurprising really, these are characteristics shared by all Apache Foundation projects. Given Tomcat's capabilities, I really didn't see a need to keep Apache HTTPD server in the picture.

                 

                In fact, I even used the URL Rewrite valve in Tomcat to make sure all our existing OHS-based APEX links out there /pls/apex/...., pls/qa/.., etc, stil continue to work. Here is how that can be done.

                 

                Step 1 - Open the $CATALINA_HOME/conf/server.xml file and add the following line right below the starting Host name="localhost" ... tag

                 

                <Valve className="org.apache.catalina.valves.rewrite.RewriteValve" />

                 

                Step 2 - Create a file $CATALINA_HOME/conf/Catalina/localhost/rewrite.config with the following rewrite rules

                 

                RewriteRule ^/pls/[^/]+/?$   /apex [redirect,last]
                RewriteRule ^/pls/([^/]+)/(.*)$ /apex/$2 [redirect,last]
                

                 

                The first rule matches URLs of the form /pls/dad which should redirect to the APEX login page

                 

                The second rule matches URLs of the form /pls/dad/<whatever> which just redirect to the ORDS webapp /apex/<whatever>

                 

                Warning: I haven't fully tested the regexps, tweak as needed.

                 

                Tim - Thanks. Your writeup inspired me. :-)

                  Hi VANJ,

                   

                  Have you tried this with Weblogic instead of Tomcat?

                   

                  Thanks in advance!

                    partlycloudy

                    Here is an alternative deployment option...if there are audit or best practice concerns around the same machine hosting both the database and web/application server (APEX/Tomcat), it may make sense to install Tomcat on a separate Windows server and use IIS as a webserver and Tomcat as a servlet engine for ORDS. After all, most Windows-based environments have several Windows servers running IIS to host ASP/.NET applications, makes sense to re-use them to serve up APEX as well, especially since Tomcat has a very small footprint.

                     

                    In this configuration, IIS negotiates (Kerberos) credentials with the browser and forwards the authenticated request to Tomcat for use by the APEX engine. This way the Tomcat configuration stays pretty much out of the box and IIS does all the heavy lifting for authentication.

                     

                    Environment

                    1. Windows Server 2008 64-bit
                    2. IIS 7 running on the default port 80.
                    3. Tomcat 8 - Installed in c:\program files\apache software foundation\tomcat 8.0
                    4. Tomcat IIS connector

                     

                    Step 1 - Download and install Tomcat binary distribution - 32-bit/64-bit Windows Service Installer

                     

                    Step 2 - Download and install ORDS as per the installation instructions. Configure ords.war (or apex.war) and make sure Tomcat can connect to APEX and you are able to get to the APEX login page using Tomcat e.g. http://server:8080/apex/apex_admin

                     

                    Step 3 - Follow the instructions here to install and configure the IIS ISAPI redirector. Copy isapi_redirect.dll to c:\program files\apache software foundation\tomcat 8.0\bin. Make sure the virtual directory you add to IIS has the alias /apex. This matches the path for the Tomcat APEX webapp. Create a new Non-Managed application pool for Tomcat/APEX and assign the virtual directory to this application pool. Make sure the application pool 32/64-bit property matches the 32/64-bit of the ISAPI dll.


                    Step 4 - Create a isapi_redirect.properties file in c:\program files\apache software foundation\tomcat 8.0 and make sure the path names in the file point to the proper locations. See here for an example

                     

                    Step 5 - Create the worker.properties file at the path specified in the isapi_redirect.properties file with the following

                     

                    worker.list=apex
                    worker.apex.host=localhost
                    worker.apex.port=8009
                    worker.apex.type=ajp13
                    
                    
                    

                     

                    Step 6 - Create the uriworkermap.properties file at the path specified in the isapi_redirect.properties file with the following

                     

                    /apex/*=apex
                    
                    
                    

                     

                    This instructs IIS to use the ISAPI redirect to pass all requests for /apex/* to the Tomcat worker

                     

                    Step 7 - Edit Tomcat's server.xml and add address=127.0.0.1 tomcatAuthentication=false to the AJP  Connector port=8009. This instructs Tomcat to a) accept AJP requests only on the local loopback interface and b) use the authenticated IIS request instead of attempting to do its own authentication.

                     

                    Step 8 - Create a virtual directory in IIS with an alias /i pointing to the physical location of the APEX /images folder (get it from the APEX software distribution). Verify  IIS access to these static files by checking http://server/i/apex_version.txt

                     

                    If this is the only use of Tomcat on this server, you can even comment out the HTTP Connector on port 8080 for enhanced security. Maybe even disable the Tomcat shutdown port (8005) and use the Windows Component Services to startup/shutdow the Tomcat service.

                     

                    At this point, if everything is configured correctly, you should be able to access APEX via IIS using http://server/apex/apex_admin

                     

                    When you login to APEX > Administration > About > CGI variables, the REMOTE_USER will probably be prefixed with the domain e.g. DOMAIN\USER. If your applications expect just the USER, you will need to adjust the authentication scheme code to strip out the domain.

                      Hi Vanj,

                      Thank you a lot for writing this up in a single thread. It means a lot to folks like me. I know you have been trying really hard to achieve this (from seeing your queries in the older threads).

                      With help of your guidelines (and a smart DBA we got here), we were able to upgrade our existing APEX environment to a new environment with Kerberos authentication.

                      Old environment :

                      DB: Oracle11gR2 in Redhat Linux

                      Middleware: OAS in Windows 2003

                      APEX: Ver.4.1.1

                      Client: IE7 in XP

                      Authentication: Custom SSO - Jason's PL/SQL based NTLM authentication (worked like a charm for last 5+ years)

                      New environment:

                      DB: Oracle 12c

                      Middleware : Apache Tomcat 8 + ORDS 2.x in Redhat Linux

                      APEX: Ver.4.2.x

                      Client: IE11 in Win 8.1

                      Authentication: Kerberos SSO using SPNEGO (HTTP Header Value in APEX auth)

                       

                      We haven't migrated to the new environment yet but the transition is around the corner, we were able to get an evaluation environment (with the new environment config) up and running.

                       

                      Once again thank you a lot for that.

                       

                      We do have a few issues, I wonder if you could shed some light on?

                      1. Currently, the Kerberos authentication fires-up even for the workspace login page as well APEX admin login page. Is there a way we could limit the Kerberos authentication to kick-in only when we run the applications. If I understand your write up this needs to be done around url-pattern  ? I am not sure how effectively we could apply this filter, since the workspace login page has pretty much the same structure as of an application running, except if you could filter on an app_id range?

                       

                      2. The SOE upgrade is staged, means part of the employees may be on new environment while the other part working in existing environment. Initially, we thought we would run two middlewares simultaneously (holding on to the Oracle upgrade). But then had to drop that plan because we could not find a way to cater multiple authentications running at same time for a given application. Here is the dump question, you know anyways of running dynamic authentication (switching between Jasons NTLM and Kerberos based on IE ver)?

                       

                      Sorry that a lot to read, I know, but I thought I would explain it as best I can rather you (if you are, I hope ) asking for it .

                        You are welcome. Glad my experience and write-up was useful.

                         

                        1. Most Tomcat configs apply either globally or to a specific webapp. If you use a filter or security-constraint, etc globally, the url-pattern can be used to restrict it to specific URL patterns. But in my example, I used a local $CATALINA_HOME/webapps/apex/WEB-INF/web.xml so it applies to just the apex webapp and that's why I use the url-pattern of /* to match everything. From what I read in Link #9 in the Reference links I posted, the url-pattern is not very flexible in patterb matching so I don't think there is a way to have the SPNEGO security constraint bypass the APEX Builder apps.

                         

                        But I am not sure I understand why you would want them to skip Kerberos?

                         

                        2. Well, the authentication scheme in this case is simply reading the REMOTE_USER CGI variable and setting up an APEX session based on that.  How that variable gets set is really beyond APEX, it is up to the web server (Tomcat, Apache, etc) to do that.  But again, I am not sure I see where you are going with this. If you want to migrate over your users from the old setup to the new Tomcat-based setup gradually, you can explore URL redirects based on source IP address/range i.e. have all APEX requests  go to your old Apache-based server and write URL-rewrite rules to redirect certain IP addresses over to Tomcat.

                          Hello VANJ..

                           

                          Thank you for the information provided.  I am able to follow the procedure to implement the apex sso in tomcat.  However, the remote_user value shows "APEX_PUBLIC_USER", not the actual user name which authenticated to the network.  Could you assist further?

                          my tomcat version is 8.

                          Do I need to configure jndi realm?  see info here

                          and window integrated authentication in tomcat first before I follow your step?

                            My write-up above provides step-by-step instructions along with checkpoints to verify the setup. Did you follow all the steps? Did the checkpoints in Steps 7 and 8 work as described? There are many moving parts here, I really can't help without examining your configuration in detail, reviewing log files and such. Good luck.

                              Hello VANJ..

                               

                              I was able to deploy APEX into weblogic which is Kerbero SSO enabled.  I compared your steps and my steps in weblogic and read your instruction carefully one more time.  I hope you don't mind sharing server.xml and context.xml under your tomcat instance, conf directory, because you mentioned about the "loginConfigName on the SpnegoAuthenticator valve".  I just don't think my tomcat read my apex.xml from localhost directory.

                               

                              also I find the URL is interesting, I have to add trailing "/" to access the APEX.  (http://localhost:8080/ords/ work, but not http://localhost:8080/ords ...)  For the situation like that, should I put "ords/" as appName or just "ords" as appName..

                               

                              Thank you in advance for your help.  I look forward to hearing from you

                                My write-up was for Apache Tomcat, not Oracle Weblogic. I know nothing about the latter. But assuming they are similar, here are a few comments

                                 

                                1. I didn't make any change to server.xml.

                                2. context.xml is not applicable here, see my explanation above - APEX is "auto-deployed" using the supplied WAR file and Tomcat explodes this into a apex directory in $CATALINA_HOME. Auto-deployed web apps don't have a explicit Context element defined. Fortunately, we can override that by creating a file $CATALINA_HOME/conf/Catalina/localhost/apex.xml with the following. The name of the file (apex.xml) has to match the WAR file so if you renamed ords.war to apex.war then the filename shouldl be apex.xml otherwise it stays ords.xml

                                3. Leaving off the trailing slash works fine for me. What happens when you leave it off? Does it give a 404?  I see that Colm has a blog post talking about how trailing slashes affect REST endpoints, see if that helps.

                                4. The loginConfgName and appName are set to APEX. The name doesn't matter as long as it is the same as the one used in jaas.conf as I mentioned in Step 11

                                  thank you for your information.  I am getting understand better on this SSO deployment...  You are correct.  I don't need to worry about server.xml and context.xml...

                                  I got better log information for deployment on tomcat...  However, it still prompt me the login info...  I am confused...  I thought I set doNotPrompt="true" in jaas.conf...  Here is some log...  Hope you could point me the correct direction..  at the end of log...  the ticket is found.  But I don't see it find me as a user ("Search Subject for SPNEGO ACCEPT cred (<<DEF>>, sun.security.jgss.spnego.SpNegoCredElement))
