I'm assuming you followed the Oracle docs on domain joining?
http://docs.oracle.com/cd/E23824_01/html/821-1449/configuringoperationmodetm.html

In my experience, idmap failures are a result of only a few things:
1. The username/group is misspelled somewhere in idmap. Verify in idmap
list that it's winuser:[email protected] unixuser:user the FQDN is required
for the Windows user portion IE not just domain\user or user@domain, but
domain.com\user or [email protected].
2. Connections to the DC are failing either because of networking issues or
because kerberos wasn't happy about something. Usually clock skew.
3. A problem with the Windows user account, locked out/must change password
at next logon/expired password
4. DNS on the OI box being pointed somewhere other than a GC DC.

Check idmapping with idmap show -cV uid:UNIXUID  to see what's happening
when idmap tries to do the lookup.

Is the OI box able to look up Windows hosts by shortname?

 Do your XP clients face the same connection problems?

See if disabling SMB security signing checks on a couple clients eliminates
the issue. Office is particularly finnicky about this, and I have no idea
why. The registry changes in the Workaround section of this technet article
will do what you need. http://support.microsoft.com/kb/982860 Disabling
signing will make MITM attacks easier.
