It'd be useful for us if the IMAP passdb could be used as a prefetch userdb.

The remote IMAP server could respond with something like

• OK key=value
• OK key=value SEQ OK [CAPABILITY ...] Logged in.

Or

• OK <some JSON key value pairs> SEQ OK [CAPABILITY ...] Logged in.

Would anyone else find this useful?

Uh. Why not simply something completely different like HTTP-based passdb?

I can't find info for HTTP on the wiki, can we set that up as a success/fail passdb? We do our own password auth (so we can support custom hash types, etc).
