As part of a server upgrade I spent most of yesterday moving servers to a new rack at the Minnesota Daily. However, after the dust settled our jabber server (jabberd2) decided it no longer wanted to authenticate users. I must admit that I'm getting very tired of dealing with this server. It's bad to say the least. Poor documentation, strange configuration and other fun things.

So I'm wondering if anyone has any suggestions for a jabber server. I'm leaning towards ejabberd or openfire as these seem to be well maintained and both seem to pretty nice (or I suppose if anyone wants to make a plug for either ;). The only real requirements is that it must be able to authenticate via RADIUS (if it does it through PAM that's OK) and have some way to automatically update rosters (even if this means a custom script that just messes with the database backend). Something which can use MySql as a backend would be preferred but isn't necessary.

I'd be interested to hear what kind of experiences people have had with these.
