Sorry to jump in the middle of this thread, but the nssov overlay sounds
very useful, something I would like to take advantage of, but I cannot seem to find any documentation on it. How long has this been available (what release), and where might I find more info?
It has not been released yet. You can check out the current code from CVS in contrib/slapd-modules/nssov. You can browse it online here:
http://www.openldap.org/devel/cvsweb.cgi/contrib/slapd-modules/nssov/
The README and slapo-nssov.5 manpage will give you a better idea of what it does.
Thanks, John

Hello, I've been working on implementing a LDAP solution for the
last
8 months (in-between task, you know how it is :D )
Time flies!
I now have a working LDAP directory, have all my users imported, things actually work! :D..(jinx!)
Excellent work, well done!
But now I wanna get fancy..
I've been googeling for some sort of clear description on how I can set up a system using groups of hosts and user groups to create a selective ACL for ssh'ing to a set of servers based on group membership.
It sounds to me like you are almost here and just need help creating
the LDAP groups, ACLs
and LDAP search/filters for use with nss_ldap on RHEL 4/5 and Centos?
ACLs for nss_ldap is not the way to handle this. It needs to be done in the PAM account management handlers, and pam_ldap's support for that is pretty weak. In particular, it doesn't support centrally configuring access to services on groups of hosts. The PAM support in nssov is a lot better in this area and can do what the original poster wants; I just haven't written an example ACL for this feature in the docs yet.
