SASL config options in /etc/imapd.conf

Looking at git blame, that line has been commented out for as long as
the file has existed in the repository.  There is a comment above it
saying that it's commented out because it's used by libsasl, but I don't
understand the implications of that myself.  Maybe that it's not needed
in lib/imapoptions because libsasl takes care of it?  In which case I
guess it exists as a comment in the imapoptions file as documentation
that the option exists, even though it is not handled by this file
particularly.

I noticed in the "Running a basic server" document you wrote that you
were using:

> sasl_pwcheck_method: saslauthd

Which is interesting because I had trouble getting that working when I
tried it (for reasons that ended up being unrelated, I think, but I
didn't try it again to verify).  I have my VM's configured with this,
based I think on the config/docs shipped with debian's cyrus-imapd
package:

> sasl_pwcheck_method: auxprop
> sasl_auxprop_plugin: sasldb

I'm not sure what the difference is myself, just that this seemed to
work (though I have not touched virtual domains yet).

I also see you're using:

> virtdomains: yes

There was a thread started by Willem Offermans on info-cyrus last week
asking about an issue with virtual domains, in which Bron suggested
instead using:

> virtdomains: userid

I don't know if it will help, but if you haven't already maybe give that
a try too?
