Troubleshooting: Cannot start WebSphere Portal server due to a missing cn=wpsadmins,o=defaultWIMFileBasedRealm

The WebSphere Portal Server Administration Console fails to open after configuring WebSphere Portal using the configuration wizard.

The SystemOut.log shows the following error:

00000026 Servlet  E init EJPFD0016E: Initialization of service failed.
EJPSB0107E: Exception occurred while retrieving the identity of the domain admin user/admingroup cn=wpsadmins,o=defaultWIMFileBasedRealm.


You can either put this group back into your local repository or change your WPS admin group to something that exists. The fileRegistry.xml file can be found in the wp_profile/config/cells directory. To add the wpsadmins group, open the WebSphere Application Server Administration Console and select Add Groups.
