When I run the following "net lookup sid" command, I get: # net lookup sid S-1-5-21-1908027396-2059629336-315576832-12220 S-1-5-21-1908027396-2059629336-315576832-12220 1 (User) \fhess This is wrong in that "\fhess" should be "NIST\fhess". The other direction works fine: # net lookup name "NIST\fhess" S-1-5-21-1908027396-2059629336-315576832-12220 1 (User) NIST\fhess wbinfo works fine in both directions: # wbinfo -s S-1-5-21-1908027396-2059629336-315576832-12220 NIST\fhess 1 # wbinfo -n "NIST\fhess" S-1-5-21-1908027396-2059629336-315576832-12220 SID_USER (1) Another sympton is on windows clients, in the security tab of the file properties dialog, it will just list the short user names of users, for example "myusername", instead of the person's full info, for example: "Doe, john (myusername at xyz.com)". This is on a file being served by the samba server with the "net lookup sid" problem. I am using samba from Debian Squeeze (3.5.6). It used to work fine with the Debian Lenny version (3.2.5). The output of "net lookup sid" with debug turned up to 10 is attached. Anyone have a clue what is going on? I'm happy to provide more info if needed to debug. -------------- next part -------------- # net lookup sid S-1-5-21-1908027396-2059629336-315576832-12220 -d 10 [2011/03/07 15:56:02, 5]
