Cannot login to AM when using a custom Root Suffix for configuration

If we install AM using a custom installation with a non default root suffix, then the user is unable to log into AM.

Steps to Reproduce

1. Start the Tomcat server in File Based Configuration mode:

   JAVA_OPTS="-Dcom.sun.identity.sm.sms_object_filebased_enabled=true"
   <path-to-apache>/bin/catalina.sh jpda start
   

2. Then perform a custom installation, setting the "Data Store Settings" "Root Suffix" value to dc=badgers,dc=org.
3. Select the "Embedded User Data Store (DS)" for the configuration store.
4. Complete the rest of the installation as usual.
5. Attempt to log into AM.

Expected Result

Login completes successfully.

Actual Result

Login fails.
