Can you provide some more info about idmap_ad ?
I search google and couldn't find a good starting point to learn about this
A quick overview about my setup is that I'm using Microsoft Windows Server
2003 RC2 with RFC2307 so all my users have UID, GID attributes
configured. On my Linux machine I have used LIBNSS_LDAP and PAM_KRB5 which
provide my users to authenticated based on there active directory user. Now
I have setup Samba3 on the server and make a simple share. When trying to
make the share compatible with CIFS NTFS Like permission (Domain Users
having Full Control permission etc...) I get errors and everything seems
to fail. I guess this setup doens't know rellay how to SID to UID so I must
Can you please provide a small example how to configure samba share to use
RFC2307 with NTFS style permission (taking into account that the linux
server is part of the domain, having NTP setup, pam module, nsswitch.conf
My FileSystem is at the moment XFS but I once I will get that to work - I
plan to move on to ZFS on Solaris.
Then My next goal is to check this via Samba4 instead of Micro$oft Server.
Thanks for the help
