When attempting to implement LDAP onto SSO for a CA NetQoS Product you can run into this error while attempting an "Option 5: Test LDAP" from the SSO Tool:
Uncaught Exception: java.lang.NullPointerException
CA NetQoS Product Suite
Windows Server 2008
Windows Server 2012
Older versions of Performance Center use a SSO Timeout setting of '5000' which causes issues with the newer products. The '5000' timeout value can sync down from Performance Center to the product as a Remote Value and can be the cause this problem.
