[Samba] Idmap probs with smb3beta

[Collen]

Well just trying to get the new beta working..

if i use the passwd plain text file, no probs.
but i realy like to use the tdbsam (passdb.tdb) file..
i put passdb backend = tdbsam:/path to passdb.tdb

now my error log complains about: Idmap gid range missing & uid range missing.

i mapped the ntdomain groups to unix groups..

also i get these same errors using pdbedit...

second and more problematic is that, as soon as i use tdbsam the domain 
goes down,
can't look around, no server in the list...

so how can i map these missing gid & uid ranges.. ??
i thought you mapped your id's through the 'net command'  and with pdbedit ?

Got some tips ?
