Hi all, I already can successfully join Samba 3 (3.3.x) server to AD domain and setup winbind service to see domain users on linux server. The main problem for me is that I want to save all already existing uids and gids on linux server without any change. Firstly, I can map domain user to unix user with "username map" option vova = CORP\vova But this trick doesn't work for groups, only for users. But even this doesn't work for next share definition: [testshare] path =/home/testshare guest ok=no write list = +CORP\testgroup force create mode = 0660 force directory mode = 2770 force group = +CORP\testgroup create mask = 0660 directory mask = 2770 Domain user vova is member of domain group testgroup, so he would get access to share but when he is mapped to unix user vova (with "username map" option), he wouldn't. So "username map" looks useless for my problem. I tried other methods of mapping accounts (net groupmap; wbinfo --set-gid-mapping) but they all nonfunctional. Also I don't want to setup LDAP backend only for this mapping. I struggle with this already some days, but still can't get solution and clean answer. Is this possible to join Samba to AD domain while saving local uids and gids? Or it's easier to just "rechown" all files on server? Thank you all. -- Vladimir Vassiliev
