Umm, isn't there an option on the configuration to disable referrals? If 
not, do you have that patch available?

Also, one question on the communication between the frontends and 
backends. I made them speak using TLS and plain, but would like to use 
CRAM-MD5 or DIGEST-MD5 and no TLS at all. Is that possible?
Because when I disable TLS and force it to use the MD5 thing, the 
frontend complains that there are no mechs available.
