Hi I'm using winbind with LDAP backend for UID/GID<->SID mapping. The only problem I have so far is, it logs to syslog tons of messages that it cannot find some uid-sid mappings: mapping not found for uidNumber: 3300 I was thinking to create mapping for such uids/gids using a NULL SID but this can be done just for one uid, as the DN in LDAP is composed of sambaSID and ou. Thus the SID must be uniq and as I lerned from google there is only one NULL SID. Has anyone any idea how to trick winbind or make it be quite? Thanks for your time. Regards, Chris
