That disturbs me. Primarly because this concept rattles my world view.
I have a vague understanding of user and permission in the first place.

Let's see if I can noodle what you are tell us.

When you log in a UID is created and you have permissions.  In
the "box is world" view, the box stores information about valid
users.  LDAP centralizes and globalizes authentication so that a
box can allow an infinite number of users - theoretically speaking.

pserver being too dumb to use LDAP is not surprising.  It seems that
it has been abandoned by serious folk except as an anonynous read-only

ssh is surely LDAP aware.

Maybe the test should be this:

 $ cvs -f :ext:your_ldap_existence at cvs_server:/var/cvs_rep co module

There are setups that underlie the correct operation.  In a Debian
machine the magic is automatic at install time.  On old RH boxes
there are some environment vars that force ssh usage instead of rsh

Keyagents are security compromises to the truly paranoid.  If you
walk away from you machine you've enabled an unauthorized person to
access the secure area using your machine.


Moving forward in pushing back the envelope of the corporate paradigm.
