Hi Samba Users,
I am currently in the process of migrating from an NT4 Domain to a
Samba/LDAP Domain.
I am already running a number of samba servers which are domain member
servers in the existing domain. They retrieve their account information
from the NT4 PDC using winbind.
So far i have completed the NT4 to Samba/LDAP migration as described in
chapter 9 of Samba by Example up to the point where i have powered off the
NT4 PDC and made the Samba/LDAP Domain Master.
However at this point the Samba Domain Member servers begin to lose all
the window's users. i.e getent passwd no longer returns the windows users.
I then restart winbind in debug mode to discover what is happening:
-----------------START-------------------
ian@viao:/etc/samba$ wbinfo -t
checking the trust secret via RPC calls succeeded
ian@viao:/var/log/samba$ sudo winbindd -i -d 3
winbindd version 3.0.10-Ubuntu started.

Everthing appears normal up until prs_mem_get. Does anybody know what this
means ?.
I am using samba 3.14a on RHEL4 (binaries from www.enterprisesamba.com) as
my SAMBA PDC and samba 3.10 FC2 and Ubuntu on the domain member servers.
The New Samba domain appears to work correctly (login script etc..)appart
from the Samba Domain Member server (Where all my files are !!)
In the the medium to long term i plan to access LDAP Directly and not use
winbind at all. I still need winbind though until i have successfully
completed the migration.
Thanks in advance for any help, comments or feedback.
