We've just built a RHEL 5 ES server to test the issues we've been having with group permissions since 3.0.23 (re: 3.0.23d UNIX vs. AD group permissions) and we found we have the same issue with the Redhat built rpm of version 3.0.23c. The following is the ldap and winbind portion of our smb.conf, the same as used on our current Solaris production servers: # ldap settings ldap admin dn = cn=ldapmaster,dc=mel,dc=nist,dc=gov idmap backend = ldap:ldap://ldap1.mel.nist.gov ldap idmap suffix = ou=Idmap ldap suffix = dc=mel,dc=nist,dc=gov idmap uid = 16777216-33554431 idmap gid = 16777216-33554431 template shell = /bin/false winbind use default domain = no winbind trusted domains only = yes We don't allocate uids or gids with this setup, only map the sids so that a user can work with ACLs on the Windows workstations. (The NIS uids and gids are handed out from a superior database to ensure common account ids across labs with no common authentication system.) We have all usernames manually the same in NIS and in AD, and we don't have any groups in AD. The UNIX file system permissions have always worked before 3.0.23, specifically if you are a member of a group in NIS then you can access the files and directories on the SAMBA server from a Windows AD workstation. Since 3.0.23, if winbind is running, the SAMBA server will get a list of groups from AD and not from NIS. If winbind is not running, it gets the list of groups from NIS. We don't maintain groups in AD, so any shared directories will not allow group members. I think I've checked all of the release notes and the updated man pages and while there are lots of changes in the 3.0.23 to 3.0.25 versions, I can't find anything that indicates this should be happening. I'd be glad to create level 10 logs to show what's happening (as I did in the previous posts and the bugzilla entry 4348). If anyone has any suggestions I'd greatly appreciate it. We're still running 3.0.14 and can't update production until we can sort this out. -- David Pullman
