Problem with mailbox name using virtual domains (sasl plugin problem?)

[Adam D. Oliver]

I'm trying to get virtual hosting up and running with cyrus imapd and sasl.
The problem is that I create a mailbox for a user that will be in a domain
other than the default domain.

cm user/username at domain1.com

When I log in as the user (testing with Outlook Express) it wants to use the
following format instead.

user/username/foldername at domain1.com

I've been searching and the only thing close to even discussing this is
mention that some auxprop plugins do not pass on the domain/realm to the
imap server.  If that is the case how is it getting the domain name to tack
onto the folder name?  I am using the sasldb plugin.  I added the user to
sasldb with the following:

saslpasswd2 -c -u domain1.com username

I log in through outlook express using username at domain1.com as the username.

Cyrus SASL version 2.1.20
Cyrus Imapd version 2.2.10
