Apex 4.2 LDAP Authentication is not working

99770Dec 12 2012 — edited Dec 12 2012
Hello,

i have a application with LDAP Authentication. It worked on 4.1.
After an upgrade to 4.2 the user cannot connect to the application anymore.
Error: "Invallid Login Credentials"

The Username is "Domain\username"
Example MYDomain\john
In the Authentication Schema i tried to change the Username Escaping
to Standard, Only Special Characters and Escaping. I tried all three settings, with no luck.

I installed the Patch p15836959_420_Generic from 27.Nov

But i cannot get into the app.

Hi Volker,

can you run the login page in debug mode (LEVEL9) to see what happens? I first thought this could be bug #14798940 but in that case the problem would have gone away after saving the authentication scheme.

Ho to do Level 9 Debug?
Hi Volker,

the app's URL will look a bit like this:

http://host:port/apex/f?p=app:page:session::NO::

Change NO to LEVEL9. Before 4.2, you could only say YES, which is level 4, or NO. LEVEL9 gives the most detailed output.

Hi,

the post-installation steps described here

http://docs.oracle.com/cd/E37097_01/doc/install.42/e35123/otn_install.htm#BEHHJJIH

to configure the ACL for APEX_040200 seem to be missing.
