I already list my servers in "password server =", altough I do have the
impression that Samba may have problems with my 2008R2 servers. I'll try
playing with the settings.

Do you mean fill in /etc/krb5.conf properly or should I refer to it
somewhere in the smb.conf file? I'm sure my krb5.conf is correct is I
was using it in my old setup using kerberos+ldap authentication. I
found some reference on the Internet to an smb.conf variable "use
kerberos keytab = yes" however this doesn't seem to be accepted for
Samba 3.4.7

I think that's expected behaviour. idmap_ad looks upo uid/gid from AD
but doesn't create its own mapping if it doesn't find one. So any user
that doesn't have a proper unix uid/gid field won't show up. I also
noticed idmap_ad looks at the Windows Primary Group as gid in stead of
the group field on the unix tab. Therefor the Windows Primary Group also
needs to have a valid unix id assigned.
