Hi,

after an update from dovecot 2.1.16 to 2.2.0 I encountered a problem when using multiple master user passdb's like the following:

----%<--------------------------------------------------------- passdb { args = /etc/dovecot/passwd.foo-master driver = passwd-file master = yes } passdb { args = /etc/dovecot/passwd.bar-master driver = passwd-file master = yes } ----%<---------------------------------------------------------

The former behavior that the passdb's are searched sequentially to find the given master user doesn't seem to work anymore. Only the first passdb is searched, and thus authentication will fail for all master users which are not defined in the first passdb.

Because I cannot find any hint that the master user handling has changed fundamentally it looks like a bug, but maybe I missed configuration related changes from 2.1 to 2.2 that is causing this new behavior.

Cheers, Chris
