Hi, I've configured samba with ldap support and all is going well with normal users. I wanted to know how to give special right/privileges to users using any windows tool. I tried to use w2k's support tool (Active Directory Users and Computers) and nt's srvtools(usermgr) but none of these worked. win2k says "can not connect to pre-windows 2000 domain" nt connects and gets everything as expected but it just can not set/change anything (except password and some user flags). When i try to change group membership and add user to "Domain Admins" group is says "The Group name can not be found" users is the output of my groupmap list. Domain Admins (S-1-5-21-4276035903-123456789-2739979074-512) -> Domain Admins Domain Users (S-1-5-21-4276035903-123456789-2739979074-513) -> Domain Users Domain Guests (S-1-5-21-4276035903-123456789-2739979074-514) -> Domain Guests Administrators (S-1-5-21-4276035903-123456789-2739979074-544) -> Administrators users (S-1-5-21-4276035903-123456789-2739979074-545) -> users Guests (S-1-5-21-4276035903-123456789-2739979074-546) -> Guests Power Users (S-1-5-21-4276035903-123456789-2739979074-547) -> Power Users Account Operators (S-1-5-21-4276035903-123456789-2739979074-548) -> Account Operators Server Operators (S-1-5-21-4276035903-123456789-2739979074-549) -> Server Operators Print Operators (S-1-5-21-4276035903-123456789-2739979074-550) -> Print Operators Backup Operators (S-1-5-21-4276035903-123456789-2739979074-551) -> Backup Operators Replicator (S-1-5-21-4276035903-123456789-2739979074-552) -> Replicator Domain Computers (S-1-5-21-4276035903-123456789-2739979074-553) -> Domain Computers Users are created with the membership of "users" group by default. # id savas uid=1014(savas) gid=545(users) groups=545(users) Am i supposed to give membership from unix as well? like say "Domain Admins" ? As a reminder, i can use shares, and can logon to samba pdc domain with users successfully, what i cant do is, change some settings of users using some tool. I'm starting to wonder if there is another tool for samba pdc? Thanks.
