Rational Focal Point supports Rational Directory Server as LDAP server. If you have configured Rational Focal Point 6.6 that is deployed in Websphere Application Server to use the RDS server, you might encounter a problem while logging in. The "Login failed" or "An Error occurred" message is disaplayed when you login with a wrong password.
This error is due to the incompatible versions of the Websphere Application Server and Rational Directory Server.
Resolving the problem
Use Websphere Application Server v22.214.171.124 and Rational Directory Server 126.96.36.199.
To use RDS as the LDAP server, see the supported compatible version of Websphere Application Server and the Rational Directory Server mentioned in the System Requirements topic in the help.
