After having active directory users duplicated in a general ldap environment we update the user's properties (in CA Release Automation) to point to the appropriate LDAP server, port, search context, and security context (the user's dn). The user's name/id remains the same. Then we try to login with that user but the user does not authenticate successfully.
CA Release Automation v6.5.0
General LDAP (Oracle LDAP, apacheds ldap, etc..).
Migrating users from Active Directory to General LDAP has not been officially tested and therefore is not officially supported.
