Re: SASL authentication

do a truss(1) [or similar] on it to see where libsasl looks for its
plugins and exactly which plugins its trying to find. libldap does
not have any requirements on where those sasl plugins should reside
in fact it doesnt know about them at all. it knows sasl mech names
and its up to libsasl to map them mech names to its plugins and to
take care of locating and loading related plugins. you should also
try SASL_PATH trick Rich suggested to you.

Originally, I put them into the same path, i.e. "/opt/nc/lib/" (this is the path of our own libraries, instead of system libraries). It didn't work. Then I created a folder called "sasl2" under "/opt/nc/lib", and put the gssapi plugin into it. It still didn't work.
