Problems with kerberos auth - possibly against ADS - since nfs-utils-1.2.3

Hi, 
 I have some reports of problems with kerberos auth in openSUSE 11.4 (using
 1.2.3) which can be fixed by using the openSUSE 11.3 version of rpc.gssd
 (from 1.2.1).

https://bugzilla.novell.com/show_bug.cgi?id=614293

 The important difference seems to be the list of enc_types used in
 limit_krb5_enctypes.

 In 1.2.1 this list is hard coded in the rpc.gssd to 1,3,2 (I think).
 In 1.2.3 this list is taken from the kernel where is it hard coded
  to  18,17,16,23,3,1,2.
 When I patch the 11.4 code to use the old enctype list, it works perfectly.

 So presumably it ends up negotiating one of those other enc_types and
 gets confused by it.

 I'll try to get a comparative tcp dump to see if that helps, but
 if anyone has any idea what the problem might be I'd love to hear
 suggestions.

 The systems are running a 2.6.37 kernel in case that might make a difference.

Thanks,
NeilBrown
