cyrus virtual domains -- real not passed to saslauthd with virtdomains: userid

[lartc]

hi all,

no joy even after googling for hours and looking thru the archives ...

i cannot get imap to pass the realm either in the userid or realm field
to saslauthd.

i can successfully authenticate user at domain.com using testsaslauthd,
however, imtest test fails and debugging saslauthd does not show the
realm.

below are my configs.

any help greatly appreciated :-)

cheers

charles
