OS X 10.2 and Kerberos questions

>Hey guys,
>Two questions regarding OS 10.2 and Kerberos
>1) How do I get kerberos AFS extensions? (the one in particular is kafs.h)

If you are try to build Arla with Kerberos for Macintosh -- the 
Kerberos included with Mac OS X, get krbafs 
<http://web.mit.edu/openafs/krbafs/>.  Krbafs will provide the kafs 
shim layer which comes with KTH-KRB (and Heimdal) so that Arla can 
build with Kerberos for Macintosh.

>2) Is it possible to upgrade the kerberos on 10.2 to something like 
>Heimdal059 or the like?  what procedure would you recommend?

Kerberos for Macintosh is based on MIT Kerberos, so installing 
Heimdal over KfM would result in major changes in behavior and 
functionality.  In addition, your Heimdal installation could be 
removed or corrupted by Apple's Software Update if it tried to 
upgrade Kerberos for Macintosh.  I recommend instead installing 
Heimdal into another location such as /usr/local.

Note that Heimdal and Kerberos for Macintosh cannot share tickets 
because Heimdal uses a ticket file and Kerberos for Macintosh uses an 
in-memory ticket cache.  This means that if you use Apple services 
which use Kerberos for Macintosh and your own services built against 
Heimdal, you will have to type your Kerberos password twice.

Hope this helps,
