I found another case with the error message -1 and it was resolved with
The RUN directory for some reason was read only. After changing it to read/write, now it is working fine.
Another case with the error message was resolved with
Somehow the sm.ini file became corrupted thus preventing the ldapbinddn (and other ldap paramters) from being invoked. Once these parameters were re-added to the sm.ini file the authentication completed.
1- Remove double quotes ( " ) from the ldapbinddn parameter.
2- Remove ldap mapping setup for the operator table and make it as simple as possible. Just mapping name to sAMAccoutName
last one is ...
enable ldapauthenciateonly parameter
Hope one of these helps
