We use Red Hat Directory Server here at Red Hat as the back end of our SSO implementation. Anytime you log in to redhat.com or RHN, you are binding via LDAP.
We are running a master/master setup and have no performance problems with the amount of logins we get on a daily basis. Let me know if you have any questions about our implementation for the supporting stack. -- grant /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
