2.2.1 BETA Auth Problem

[j]

Hello All.

 I seem to be having an issue with the 2.2.1 beta server;
  Any time I try to login or authenticate any user in any way I get the
following message: "Login failed: can't request info until later in
exchange ..."

  I tested my setup under the 2.1.15 version and it works perfectly, and
I'm at a bit of a loss as to what might be causing this problem, so I
thought I'd ask the experts :)
  I know the message is coming from sasl, but as I said, my setup works
under the "stable" versions, so I didn't really know where to start
looking for a solution.

  Also, in case this isn't something I can solve quickly, could someone
direct me to an actual url where I might be able to download the patch
that allows '@' characters in the account name? I can't seem to locate
it on the net..

Thanks so much!
