Dear friends I'm trying to include a Win XP Pro into my Samba PDC with no luck. Can somebody give me a hand with this issue ? The log file for this machine gives me the following lines: Lib/debug.c:debug_parse_params(198) debug_parse_params: unrecognized debug class name or format [2] rpc_server/srv_samr.c:api_samr_set_userinfo(670) api_samr_set_userinfo: Unable to unmarshall SAMR_Q_SET_USERINFO. Passdb/pdb_smbpasswd.c:pdb_getsampwrid(1416) Unable to open passdb database Guillermo
