LDAP - This would be my ultimate solution.

OK. You're chicken.

All joking aside, I agree that LDAP OOTB would be nice for XOOPS 2.1 or whatever version. Though I have no need for it on my current site, it is not hard for me to imagine myself in a situation in which it would become a nessesity. At any rate, maybe you could ask the guy who wrote this if he has any plans to renew development on the XOOPS LDAP module. Failing that, whining (in the best possible way, of course!) in the RFE forums might help.

if you just use http://webmessenger.blitzaffe.com/ you only need to tie in it's database tables for user registration and such...and configure to add the jabber server
