OpenLDAP 23 client with 24 server?

[Matt Juszczak <matt@atopia.net>]

Hi All,

Most of our boxes are FreeBSD.  FreeBSD has ports for openldap22, 
openldap23, and openldap24.  Not using slurpd much anymore in my setups, I 
decided to run with openldap24 in our recent setup.  Setup openldap24 
server, and all the FreeBSD clients have openldap24 clients.  Everything 
is working well.

Recently, we had to introduce a few RHEL boxes into our setup.  We're 
pointing to the redhat repositories, but they seem to only have 
openldap23-* client packages.  I know I could potentially make my own 
packages, or perhaps get RPM's from the Internet, but I was wondering if 
by some chance openldap23 clients (and pam_ldap/nss_ldap libraries) are 
compatible with openldap24 servers?  I would assume the other way around 
(openldap24 clients with openldap23 servers) would work fine.

Thanks!
