ldapsearch using GSSAPI failed to run from other machine ...

hello All,

Finally I had the "openldap-2.2.5 + cyrus-sasl-2.1.23 + krb5-1.6.3"
running on my AS5_64 machine. But now I can only do ldapsearch with
GSSAPI on the same machine as the slapd and other suite running, if I
ran it from other machine, then it failed with (Unknown code krb5 7).
Of course, simple auth worked well.

This is a dummy question. I just newly contacted with sasl+krb5 with
ldap. Can anyone else kindly people tell me how to make ldapsearch
working from other machine? E.g, what kind of setup/procedure I should
do on the other machine before I can do ldapsearch with gssapi
effectively?

FYI, on the other machine, I had the same version of
"cyrus+krb5+openldap" installed, so I think the "ldapsearch" links to
the enough libraries to do sasl.

Run on the same machine, it seems working.
