I doubt it. > On Active directory side no error, only successes logs. Are you saying that a user attempts to log in, you see successful LDAP bind on the LDAP server, and RT login fails? If so, please send us the relevant debug-level RT log excerpt. Also the LDAP server log excerpt if possible. > Do you no about any other debug options I could use ? I did notice that, after upgrading to RT 4.0.17 and ExternalAuth 0.12, I get much more detailed debug-level log messages for ExternalAuth. Hope this helps. Nathan
