I was not answering to your question, because I tested that with Samba
3.6.0, not 3.5.6.  Anyway, with a fresh install of Win7 everything
worked fine here.

I also noticecd that log message but it seems to do no harm.

I had this problem after I was heavily playing with the Win7 client:
changing domain membership back and forth, adding, removing and
re-adding users (also with different uidNumbers).  Then, with some user
I got a message about a group policy client could not start, with some
user I got the message you mentioned above and with some users I still
could log in.

I'm not sure if Win7 caches such information but after I used a fresh
Win7 installation everything was OK without any change on the samba
