Hello @list! I am using Active Direktory + Samba + Winbind to make a fileserver service about 500 user with many single permissions... Yesterday we have a big powerbreak and all our servers are shut down and start again... After the start I see it all the permissions are corrupt... It looks like the USERID-USERNAME duble are drift... :( Here is my smb.conf: [global] realm = xxxxxxxxxxxxxxx workgroup = AFH server string = BB-FileServer netbios name = B-BALFILE1 load printers = no printing = none disable spoolss = yes printcap name = /dev/null map to guest = Bad User password server = xxx.xxx.xxx security = ADS encrypt passwords = yes winbind separator = + idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes name resolve order = host hide unreadable = no vfs objects = default_quota default_quota: uid=11221 default_quota: gid=10115 browseable = yes domain master = no local master = no preferred master = no os level = 0 How make the samba the USERID and the USERNAME to pair??? Can I change the /algorithm somehow???/ Why is it that, after a reboot a USERNAME which come from the AD has another USERID... Please help, regards, Bal?zs / /
