[Samba] conflicting credential setting samba as PDC

[Adi Nugraha]

hi,
I'm trying to use samba 2.26 pre 2 as a file sharing server and a PDC, when
I tried joining the domain, it asked for a username and password, after the
input there was always an error, either the user name is unknown, or
"conflicting credentials" can anyone help me with this,  got the following
from the log file
