Hmm. I used the UW IMAP c-client with PHP, and that doesn't have any hooks
into SASL that I know of. Where is IMP getting the idea to use CRAM-MD5?

I can't disable SASL support in my server, though I could remove the CRAM-MD5
plugin.

I just tried removing the libcrammd* files from /usr/lib/sasl, and now
IMP tries to use plain text! Cool, however it now fails with this message:

What the heck?
