    Authentication Oracle Linux with OUD server

    2746376

      Hi,

       

      I'm having issues getting log in auth enabled on an Oracle Linux 7.6 with OUD server 12c, here is where I stand and hope someone could guide me and locate where I have miss configured something.

      the OUD server is setup with a couple users for testing, an ldapsearch from the server or the client Linux returns results as expected example below

       

       

      [root@wfivm02500 ~]# ldapsearch -h 192.168.5.55 -p 389 -D "cn=directory manager" -w testP@ss -b "dc=gbuldap,dc=com" "(objectclass=*)"

      # extended LDIF

      #

      # LDAPv3

      # base <dc=gbuldap,dc=com> with scope subtree

      # filter: (objectclass=*)

      # requesting: ALL

      #

       

      # gbuldap.com

      dn: dc=gbuldap,dc=com

      dc: gbuldap

      objectClass: top

      objectClass: domain

       

      # People, gbuldap.com

      dn: ou=People,dc=gbuldap,dc=com

      ou: People

      objectClass: top

      objectClass: organizationalunit

       

      # user.0, People, gbuldap.com

      dn: uid=user.0,ou=People,dc=gbuldap,dc=com

      mail: user.0@maildomain.net

      initials: ASA

      homePhone: +1 225 216 5900

      pager: +1 779 041 6341

      givenName: Aaccf

      employeeNumber: 0

      telephoneNumber: +1 685 622 6202

      mobile: +1 010 154 3228

      however when I enable ldapauth any log in attempt returns the below error in the messages log

          Hi

          from logs seems connectivity issue

           

          I presume OUD is on one machine, linux box where we see

           

          Aug  1 13:48:21 wfivm02500 nslcd[1763]: [8b4567] <group/member="qemu"> failed to bind to LDAP server ldap://192.168.5.55:389/: Can't contact LDAP server: Transport endpoint is not connected

           

          is on other machine

           

          - on OUD server is any firewall running, if yes open 389 ldap port on it

          - is any firewall between OUD servr machine and linux box ? if yes,  open 389 port on that firewall
