[Samba] Samba as domain controller

[Andreas Fladischer]

hi at all!

i set up a system where samba is a primary and a secondary domain 
controller; the authentication is over ldap and everything works fine 
but....

i would like to test what happen when the pdc is down and so i shutdown 
the smb service on the pdc. the logins from all clients worked well on 
the bdc but when i try to join a new machine to the domain, it can't 
contact the domain controller (ok because the pdc is down). my question 
is, wheather it is possible to configure the bdc so, that i can join to 
the domain when the pdc is down?

my second question is wheather it is possible, that all administrative 
users can join a new machine to the domain and not only the root user?

with best regards

Andreas
