RE: user authentication on irix 6.5.20 with ldap?


Current versions of Irix (pre 6.5.22) won't handle user 
authentication against LDAP as the Linux machines do.

Basically, what you end up with is a situation where UNS/NSD
binds to the directory and populates the passwd, group, etc
information almost similarly to the way it would handle NIS.
All/most of your client-side configuration information will
be handled in /etc/nsswitch.conf (to tell nsd to use LDAP)
and /var/ns/ldap.conf (for server, binddn and formatting 
information).  For the most part it's functional.  There's
no support for ssl/tls (which is misleading because of the
"security" option in ldap.conf).  Also, there is no native
utility for users to change their passwords.

I've heard that support for LDAP should improve significantly
with 6.5.22 and there is some hints on Supportfolio eluding
to this as well (if you have a Supportfolio account, go to
the knowledgebase and search for "PAM").

Email me offline if you need some configuration hints.
