Hi, I am running Ubuntu 7.10, Samba 3.0.26a. For authentication I use Winbind which is talking to a Windows Small Business Server 2003 Everything look normal things like wbinfo -g, wbinfo -u, getent passwd etc, all runs perfectly well. The problem I have is that occasionally strange thing happen on the network. Files cannot be deleted en compile jobs fail. What I see is that when I do a smbstatus -L that some files are locked with a wrong uid. So, user with uid 10000 creates a lock with an application an the lock is assigned to user 10019. How can this be possible? I it very hard for me to look in the logs to see what happens because the phenomena is only occurring when there is lots of traffic. Because of this the log are generate huge amount of data and therefore wrapping continuously. A fragment of my smb.conf is below. [global] workgroup = MICROKEY realm = MICROKEY.LAN interfaces = eth1 security = ADS password server = 192.168.1.1 log level = 1 domain master = no idmap uid = 10000-20000 idmap gid = 10000-20000 template shell = /bin/bash winbind use default domain = Yes winbind enum users = yes winbind enum groups = yes template homedir = /home/%D/%U client use spnego = yes wins server = 192.168.1.1 name resolve order = wins bcast hosts printcap name = cups printing = cups [homes] browseable = no writable = yes [printers] comment = All Printers path = /var/spool/samba guest ok = Yes printable = Yes [print$] comment = Printer Drivers path = /etc/samba/drivers browseable = yes guest ok = no read only = yes write list = root microkey.lan\\administrator [development] comment = Product development path = /home/microkey/shares/development valid users = @microkey.lan\\development write list = @microkey.lan\\development create mask = 0770 directory mask = 0770 force group = @microkey.lan\\development Help is appreciated Marcel
