Last updated on MARCH 08, 2017

Applies to:

Oracle WebCenter Portal - Version 11.1.1.1.0 to 11.1.1.1.0 [Release 11g]
Information in this document applies to any platform.
Checked for relevance on 28-Dec-2012

Symptoms

OVD (Oracle Virtual Directory) is used for user store and OVD was configured successfully as per the documentation here:

Oracle Fusion Middleware Administrator's Guide for Oracle WebCenter 11g Release 1 (11.1.1)
14.3.6 Configuring the Discussions Server to Share the Identity Store LDAP Server

The authentication seems to work fine, as when specifying incorrect password then the following error message is returned straight away:

Invalid username or password. Please try again.


However, when specifying the correct credentials then the following exception is shown in the browser after a couple of seconds:

Error 500--Internal Server Error
