Description of problem: Winbind sometimes returns the group names in uppercase, sometimes in lowercase Version-Release number of selected component (if applicable): samba-common-3.0.22-1.fc5 How reproducible: The first time we query about some specific user, the group names are shown in uppercase. After we query about the specific group (getent group <groupname>), the group name is returned in lowercase, and subsequent queries about any user which belongs to this group will have the group name in lowercase. Steps to Reproduce: 1. Add the computer to an Windows 2000 domain 2. id <someuser_with_mixed_case_groups>. The group names are returned with the original group name (the name defined in Active Directory) 3. getent group <group_name_in_lowercase>. The group name is returned in lowercase. 4. id <the_same_user_in_step_2>. The group shown in step 3 is now in lowercase Actual results: Before the getent group <groupname>, the group name are returned in mixed case. After getent group <groupname>, the group name is returned in lowercase. Expected results: The user and group names must be always in lowercase. Additional info: After I added the computer to the domain, I changed the parameter "winbind use default domain" to true, and deleted all tdb files in /var/cache/samba. Restarting winbind makes the groupname be returned in mixed case again.
This should be fixed in 3.0.24. Please reopen if you still see case mismatches somewhere. Note that Samba now always uppercases the domain name and always lowercases the user/groupname.
