Hey there, I have configured samba to behave as a DC "by the book" (by the howto in fact...). Everything seems to work fine, I am using windows XP clients, I have changed the registry settings like the howto says, rebooted and then added the station. I have managed to log into the machine with a domain user and everything looked great, when I tried adding the domain user to the local admins by: login in as local administrator. go the users/group profile and open the administrators group. (I saw MYDOMAINNAME\domain admins there so the station registration process looks good) I then tried to add my user by adding it with and without the domainname\ as a prefix I tried adding domain users as well with no success, nothing seems to work here. I did the same many times in my office where I have a windows DC and it always worked, what have I missed here? Another thing is that it pops up to ask for the domain admin password, now - maybe I forgot it but I don't remember this happening with the windows DC. smbd.log shows: [2003/04/13 19:36:12, 2] rpc_server/srv_samr_nt.c:_samr_lookup_domain(2050) Returning domain sid for domain XXXXXXXXX -> S-X-X-XX-XXXXXXXXXXX-2XX5XXXXX5-2XXX5X2XX (censored domain name and sid out... sorry) log level is only 2 but when I tried putting it on 5 it didn't give too much useful info... A possible workaround could be simply adding everyone to the domain admins group, does that involves adding the corresponding unix users to the root group? I would really hate to do that... Some details on the environment... i386 machine running slack-current (9.0 + all latest patches) samba 2.2.8a Linux 2.4.20 Regards Gil Disatnik UNIX system/security administrator.
