Hello, My samba version is 3.0.2a running on RHES 3 servers. i am using samba, and in particular winbind to validate that my squid users (authenticated with NTLM) belong to specific AD groups on a W2K server. Everything seems to work fine, except that the logfile for winbind if full of lines such as : nsswitch/winbindd_util.c:winbindd_lookup_name_by_sid(429) Can't find domain from sid Is it just a warning, or is there something to modify in the configuration ? Thanks by advance --
