the default behaviour for first passdb is:

result_success = return-ok, so the second passdb is skipped if authentication was successfull.
I guess you return some user specific variables from the second passdb which makes INBOX 
unaccessible with master login as dovecot does not know mailbox location.

maybe you should add result_success = continue-ok to the first passdb so that second passdb
is processed even if master authentication was a success.
