gssapi, alpha's, OpenSSH 3.8p1 failing

[Mark Davies]

I have OpenSSH 3.8p1 built and working with GSSAPI based authentication on 
NetBSD/i386-current and Solaris 9 but then when I try it on both 
NetBSD/alpha-1.6.2 and Tru64-V5.1 I get:

city-art% ssh -v embassy

and the server end reports:

In the Tru64 case OpenSSH is built against Heimdal 0.5.1 and in the 
NetBSD/alpha case its built against the in tree version which I think is a 
similar vintage.  The working NetBSD/i386 and Solaris versions are built 
against newer Heimdal releases.

So can anyone suggest if this is an OpenSSH bug (alpha 64bit issue?) or a 
problem with the older Heimdal?   And how can I fix this?

cheers
