In your preliminary documentation (your message dated 2014-06-25, please
correct "seet" in it), trustPosixOffset is "some arbitrary 32 bit value",
ie including 0.

In your code (fetch_posix_offset), td->PosixOffset is used to record the
value and also (when 0) to record that the value has still not been
fetched.

I have encountered this case in real life. The domain admins have set
the trustPosixOffset of the secondary domain to zero. This value is therefore
never recorded and the cldap->open occurs again and again.

Hope this helps.
