Hi, We have a samba 3alpha19 PDC with a LDAP password backend. We have several samba servers runnign as file servers and print servers all fetching their password auth from the PDC. Most of the time clients can connect to the servers, however sometimes people can not connect to printers. The errors we are getting are: [2003/10/15 13:51:50, 1] auth/auth_server.c:check_smbserver_security(259) the challenge that the password server (MC095) supplied us is not the one we gave our client. This just can't work :-( [2003/10/15 13:51:50, 2] auth/auth.c:check_ntlm_password(309) check_ntlm_password: Authentication for user [jpither] -> [jpither] FAILED with error NT_STATUS_LOGON_FAILURE and [2003/07/08 08:54:59, 0] passdb/pdb_smbpasswd.c:pdb_getsampwnam(1367) unable to open passdb database.
