The error is coming from Maximo, but the underlying error is coming from tWAS. Make sure you are able to connect to LDAP using your settings that you have setup in tWAS. You may want to check basedn or the filters. You can also involve your LDAP admin to understand what is coming into the LDAP and why it is not found.
