I recently configured Glassfish v2, Sun AM 7.1 , Sun IDM 7.1 / MySql 5.2 and Open DS on my macBook Pro. The configuration was fairly straight forward, after doing this many times on other platforms. I'm impressed how easy openDS was to setup and integrate with AM/IDM servers.
I wish I googled Jonathan Gershater's blog entry on Sun IDM setup on Mac before attempting it myself but with a little patience I managed to get through it myself.
Eduardo writes some instructions on setting up Glassfish on mac.
