Please look https://bugzilla.andrew.cmu.edu/show_bug.cgi?id=2907 There is bug described here: http://forum.psi-im.org/thread/4292 It seems there is troubles with sasl authentication on jabberd2 2.1
Pulled into 2.1.22-6. I'll let this one cook for a bit in Raw Hide before looking at pushing it for FC6.
I updated cyrus-sasl on my FC6 box with jabberd2 2.1 I can login with SASL auth now. Thanks.
