I forgot (Gnus and Emacs itself don't have that problem :)

I attach a revised patch against Emacs that DTRT inside tramp.el itself
(I think).  Please check the logic because I don't know the Tramp
internals so well.  Also we could pass `tramp-current-user' with the
:user search key to `auth-source-search', if it's known.  I don't know
if that's TRT for Tramp.

If you can offer a suggestion for the code, that's fine.  I think,
actually, that it may be a good idea to see how many people are using
tramp-imap.el.  I have no bugs or suggestions since I wrote it, except
from you, so perhaps we should ask the community and remove it from
Tramp.  If no one needs a feature...
