I'll assume that your not just trolling for an answer.

For the record, you will always have better luck with
MIT krb5 1.3.x and Heimdal 0.6.1 or later.  Both supprt
the type 23 enc type used by Windows 200x.

There are a couple of likely reasons why you are prompted
for a password:

(a) the krb5 ticket cannot be verfied (possibly due to
an improper kerberos setup on the Samba box)
(b) getpwnam() fails for the user (see logs for instances
of 'Gwt_Pwnam did not')

If you can connect to the share using the server's IP
address but IP address, this is indicative of a krb5
configuration error somewhere.  When usiong the IP address,
the client will revert to the NTLMSSP mechanism during
session setup (rather than sending a krb5 ticket).

cheers, jerry
