I don't think I made myself clear, or maybe I'm not understanding your first
paragraph properly. About to go read up on the things you've mentioned, but
in case I didn't explain anything properly... I'm just going to outline my
situation in a bit more detail.
I'm running OpenLDAP 2.0.21, and it is currently holding user accounts,
without using any pam modules or anything, on a Mac OS X Server box. MOSXS
can look for user info in a directory service like OpenLDAP. (this is not a
production system as yet, I'm looking for a workable solution...) The
passwords are currently stored as SSHA hashes.
I'm on a sub-campus of a uni. The main campus has a central Radius
authentication system, known as "Unipass", which every single student and
staff member has a login (their employee id) and a password. I have no
control over the Radius server, completely different dept.
My userid's on my LDAP server are all of the same form, the employee id.
Rather than storing passwords in the LDAP server at all, I would like to
authenticate against the central Radius server. This would mean I could have
a central user database, and all password generation would be handled by
someone else... All staff know their unipass as it gets used for all sorts
Does that make more sense now? Most of the messages in the archives I'd come
across were talking in the other direction it seemed, getting a Radius
server to authenticate against an LDAP directory, which isn't what I want to
Thanks for any pointers.
