Hello @ll, I have recently installed a RHEL 4 system with the default samba packages : samba-common-3.0.10-1.4E samba-swat-3.0.10-1.4E samba-3.0.10-1.4E samba-client-3.0.10-1.4E Now I have successfully linked this server to our Windows domain. This means that all the windows IDs are known and these users can also login to the server without problems. Now the current systems setup is in away that only people with existing GNU&Linux accounts can have access to there home folders. This setup is configured and working on several other server RHEL3 and HP-UX11.11 servers. But on the RHEL4 the link to the existing Unix account seems to be broken? Also the GNU&Linux accounts have been setup by a NIS, in case this would be important. contents of the smb.conf, basic setup actually : [global] workgroup = realm = server string = CLearCase server security = DOMAIN auth methods = winbind obey pam restrictions = Yes password server = username map = /etc/opt/samba/smbusers log level = 3 log file = /var/log/samba/smbd.log max log size = 50 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 dns proxy = No ldap ssl = no idmap uid = 10000-20000 idmap gid = 10000-20000 template shell = /bin/bash winbind separator = / winbind cache time = 10 winbind use default domain = Yes hosts allow = 192.168.1. [homes] comment = Home Directories path = %H read only = No [sharing] comment = File sharing area path = /home/sharing read only = No guest ok = Yes and the layout of the smbusers file is: LinuxAccount = DOMAIN\Windows.Account etc... also tried layout like this LinuxAccount = Windows.Account etc.. but no effect. Does anybody have any more ideas of what could be setup wrongly? Or is this related to a bug in samba? Really need some update on this issue... Thanks in advance for any advice... -- Kristof.Bruyninckx We are Microsoft. What you are experiencing is not a problem; it is an undocumented feature.
