I have setup a Snow Leopard Server 10.6.1 as a PDC without problems to authenticate Windows XP clients. Joining a Windows XP client to the SLS PDC Domain and log in from a Windows XP client to the SLS PDC Domain are working.

After the update to Snow Leopard Server 10.6.2 the authentication is broken.

opendirectory_smb_pwd_check_ntlmv1 gave -14090 [eDSAuthFailed]

By changing the Windows XP "Network security: LAN Manager authentication level" policy to NTVLM2 responses only the authentication agains a SMB share is possible, but trying to join SLS PDC Domain is still not possible.

opendirectory_smb_pwd_check_ntlmv2 gave -14090 [eDSAuthFailed]

Any ideas? Is anyone else having similar authentication difficulties?
