Kerberos support

[Phil Camus]

Okay, first thing I did a "ldd" on my sshd2 daemon, and I saw that there
were only ".so" libraries, so I recompiled Kerberos with the
"--enable-shared" argument to configure. And I used krb5-1.2.3.

Then I set the LD_LIBRARY_PATH var to /krb5/lib and it worked just fine.

I removed too config.cache, though I made a "make clean" before
each configure.

So it works : thanks for your help !

Best regards, 

Phil
