Still having problem with NT4 domain. I have Samba 3.0.20 on FreeBSD 5.3 My configuration looks like: [global] workgroup = DOM netbios name = lanserver server string = Samba Server security = domain hosts allow = 10.200.4. 10.200.5. 127. log file = /var/log/samba/log.%m max log size = 50 password server = PDC encrypt passwords = yes winbind uid = 15000-20000 winbind gid = 15000-20000 winbind use default domain = yes template homedir = /home/%U template shell = /bin/csh winbind separator = \\ winbind enum users = yes winbind enum groups = yes nt acl support = yes local master = no dns proxy = no dos charset = 866 unix charset = KOI8-U auth methods = winbind socket options = TCP_NODELAY wins support = no Successfully connected to domain DOM. wbinfo -g and wbinfo -u works properly. But id returns primary group membership, i.e. lanserver# id administrator uid=15000(administrator) gid=15000(Domain Users) groups=15000(Domain Users) lanserver# instead of ws170# uid=15000(administrator) gid=15002(domain users) groups=15002(domain users), 15000(domain admins), 15003(exchange users), 15011(wsp) ws170# And another problem. I created a share: [Test] comment = Test share path = /home/samba/test valid users = administrator public = no writable = yes printable = no create mask = 0775 force create mode = 0664 force directory mode = 0755 write list = administrator Share is visible from PDC Administrator account only if I specify valid users = DOM\Administrator. I tried Administrator, '@domain admins', '@domain admins', '@HQ\domain admins' uncussessfully. Write access to Samba tested from account above does not work never.
