So I played around with this suggestion and came across the following issues:

1) The sample config has an invalid directive. 'ssl_disable' is not
valid. I'm assuming that 'ssl = no' is the same as 'ssl_disable =
yes'. If I can get confirmation of that, I'll update the wiki if no
one else does.

2) If I set the 'user' and 'auth_user' fields to my own login, it
works fine (or at least passes 'dovecot -n'. If I set it to the
'cyg_server' user I get the error message about not being able to use
the same user. I'm not really clear on the logic used to determine
when a user can or can not be used for both. Is there an explanation
of this so I can design my layout accordingly? I tried
'first_valid_uid = 1' to see if it would help, did not. cyg_server is
already UID 1005 though, so didn't really expect it to.
