[OpenAFS] Re: Windows TGS_REQ on alternate Netbios Names

[Jeffrey Altman]

Based upon the etypes list, this is a request coming from Windows 
itself.  My guess is that since you are logged into the machine via the 
Kerberos LSA, Windows is trying to authenticate the access to the SMB 
name published by OpenAFS with Kerberos.

You will most likely have to add service principals to your KDC for the
-AFS extended host names if you want to avoid the error messages. 
Remember that all of the principals for a given host have to use the 
same password.
