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

Hello Dan,

Sorry for my ignorance on openldap GSSAPI mechanism, and just now, I
tried and I think I found why.

On another machine, I need to config the realms in /etc/krb5.conf, so
the machine knows where the kdc is.
After that, I ran "kinit user", and then ldapsearch worked fine.

Thank you a lot for your reply.
