First of all, The problem i am having is not directly related to Samba.
So apologies, however there are a lot of people on this list who know a
good deal about how windows (and related technologies) work so i'm
hoping they can shed some light on the matter.
I successfully completed a migration from a Windows NT4 Domain to s
Samba domain with LDAP backend about 2 months. The old NT4 PDC also
hosted an exchange 5.5 sp4 email server so i could not just rubbish it.
Once the migration was complete i used a tool called UPromote to demote
the old PDC and rejoined it to the new domain (Same Domain Name). All
appeared to work well...
However, When a added new account to the system they could not access
their email using their domain account whereas existing accounts were
working fine. The mail server reported this error (from event log):
A logon attempt failed because an attempt to look up Windows NT account
information failed. Error 1332.
The new accounts worked perfectly in every other sense. Even at the old
PDC i could log on with the new accounts, see the new accounts in
usrmgr.exe, and select them as the Primary Windows NT account for the
associated mailbox in the Exchange admin program.
So i though, Maybe exchange is somehow looking on the old PDC for
account data. I was able to confirm my suspicion using an application
called regmon which records access to the registry. From the following
out put i can see the lsass.exe program searching the SAM portion of the
registry for the user account.
Output using the regmon utility
20490 160.25828604 lsass.exe:48 OpenKey
20491 160.25839958 lsass.exe:48 OpenKey
20492 160.25852070 lsass.exe:48 OpenKey
Finally (and thanks for your patience :) ). How do i get Exchange (or
lsass.exe) to search the domain for accounts and not the local registry
Any suggestion welcome,
