Hi folks! I have a problem with SID to UID translation on one of my domainmember servers since I use a newer version of samba (3.4.0). The PDC is running samba 3.0.28 and uses LDAP. On the domainmember everything is working as expected (login with domain user, wbinfo -u, wbinfo -g) but when it comes to convert the SID to UID it fails: $ wbinfo -S S-1-5-21-2106500839-766785134-2740805053-6093002 Could not convert sid S-1-5-21-2106500839-766785134-2740805053-6093002 to uid The same smb.conf on other domainmembers, running version 3.0.28, works nicely. I'm not sure if I maybe missed some package, or configuration for this translation from SID to uid. But I thought that samba is able to extract the UID from the SID, doesn't it? Here is the output of testparm on the domainmember server: ----------------------------------------------------------------- Load smb config files from /etc/samba/smb.conf rlimit_max: rlimit_max (1024) below minimum Windows limit (16384) Processing section "[Test]" Loaded services file OK.
