2.2.13 authentication problems?

[Michael Loftis]

Also LMTP is NOT affected either, it appears to ONLY be proxyd (2.2)->imapd 
(2.1) -- and even then apparently only after the same proxyd talks to a 2.2 
based backend.  Everything was fine until we moved some of our production 
systems into 2.2, only an occasional error after the frontend upgrades.  It 
bothered me but I dismissed it.  The only reason it was occasional was 
because we only had a few testing mailboxes on the new 2.2 backend.  We 
then upgraded an old 2.1 backend to 2.2 and that's when the problems really 
started.
