How did you determine which path was actually used to find
libkrb5support.so.0?

What are the direct dependencies listed by "readelf -d" for sshd and
pam_krb5.so?  (the "NEEDED" lines)

It's possible that setting the LD_DEBUG environment variable to "libs"
would give you more useful information about the shared library search
paths.  You might need to point LD_DEBUG_OUTPUT somewhere useful so it
won't send the debug output to stderr.
