Groups with Long Descriptions. This error is reproducible with samba 2.2.4 and 2.2.5. Setup is Windows 4.0 PDC. Samba 2.2.4/5 server using ACL's and Winbind. Config for winbind is winbind uid = 10000-20000 winbind gid = 10000-20000 winbind cache time = 10 All other options left as default. Config for Samba. [global] workgroup = mydomain netbios name = storm server string = Titan updated server security = DOMAIN encrypt passwords = yes update encrypted = yes smb passwd file = /etc/samba/smbpasswd password server = * unix password sync = Yes passwd program = /usr/bin/passwd %u passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %n\n *passwd:*all*authentication*tokens*updated*successfully* inherit permissions = Yes preferred master = no local master = no log file = /var/log/samba/log.%m username map = /etc/samba/users.map log level = 5 max log size = 50 announce version = 7.0 allow trusted domains = no admin users = mydomain\username socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 dns proxy = No domain master = no bind interfaces only = yes interfaces = 10.251.0.38/255.255.0.0 create mode = yes template shell = /bin/bash template homedir = /home/%D/%U The winbind info is in the smb.conf file, I just broke them apart here for clarity. Long group descriptions in windows domain are as follow. Group Name = FTP Group Description = This groups allows read/write access to the ftp folder on storm ftp server. Users = Several users. 1 to 12 sometimes. Say I have a user named sam. I have 6-14 groups like the one above. I can add Sam in 4 groups and things are working fine. If I add him to another 4 to bring him up to a total of 8 he now cannot get to anything on the samba server. So I take him out of three of the groups, restart samba, and he now can get to things. I add in another one and things are working fine. I get him in the last group and now he cannot get access to services on the samba server. Can anyone confirm that this error does exist? I was having a problem with a Dell app and I was able to fix it by taking myself out of groups that I really didn't need anymore. So this could be a Windows error that we are running on, like how it reports back large group membership. Well this is totally out of my league so I will leave it up to you pros. Have fun and thanks for a GREAT Application.
