It's indeed interesting.
Can you on the samba server do:
*kinit administrator at REDPOINT.INT
* ldbsearch -k 1 ldap://main '(cn=administrator)'
Can you post the result of the two klist commands ?
It seems that somehow the canonization of your DC (main.redpoint.int)
gives redpoint.redpoint.int. Have a look in your DNS files !

can you post the content of your smb.conf ?
Also can you do this ./bin/ldbsearch -H <path_to_private_dir>/sam.ldb
'(primaryGroupId=516)' and post the output ?

The thing is that most of the time samba change it's UID when dealing
with file to match the UID of the user accessing the file.
Can you try this patch it will gives us more information of where the
error occur in our code (which function).
The fix shouldn't be too complicated to do, it's basically a become_root
with appropriate checks but it shouldn't affect your GPO stuff.
