Ouch.  Your user SID from AD is different to the one in /etc/passwd.

That explains it.  Please recreate your /etc/passwd and /etc/group
files with mkpasswd and mkgroup, or, even better, just discard them.

The problem is the domain switch which also changed the SID of your user
account.  The old SID, which you also have in your passwd, is not
returned by the server anymore.  But it's stored in your SID history in
AD and when asking for it you get an answer.

So it works.  That's cool.  I'd suggest to throw away your passwd and
group files and live happily ever after.

That's due to your SID history.  It's a bit hard to explain, but that
occurs when "they" switch to a new domain with different SIDs.  When
asking for the new and the old SID, the same username is returned since
both are your SIDs, one old, one new.

I strongly recommend not to use the old SID anymore.  The reason is that
Cygwin will create all these files with the old SIDs.  However, your
actual user token has the new SID.  Uh, as I wrote, hard to explain and
a weird situation.

Downside: Cygwin can't handle the old SIDs from your SID history quite
correctly.  Trying to support them as well would slow down the user and
group lookups a lot.  If you can live with what we just found out and
the solution I suggested, I'd be rather happy :}


Thanks,
Corinna
