CRAM-MD5 doesn't work directly with proxying. It can't work, by CRAM-MD5 design. The only way to make it work is if your passdb lookup returns a password, either the user's actual password in plaintext or some master password, that the backends accepts with plaintext authentication. > I then change the configuration so that the 2.0.4 machine proxies the > connection back to the 1.2 machine (again) and try to login to the 2.0.4 > machine and get the same errors as above.

If it worked with v1.2, it either wasn't proxying or it was doing something like I mentioned above.
