samba - Sep 2003 - Several privileged users

Hi,

I have to setup a samba-3 configuration where several users have the
right to join a machine in the domain.

I've done a test with "username map between root and a user" but
this
solution is not acceptable because the user is considered as root even
for a normal login (the user's informations (sambaProfile,...) are not
used)

Is this a workaround ?

Thank you,

Rapha?l
