Sounds a lot like my problem, which I described some days ago here on
the list, but no luck. Please report to the list if you make any progress.

Hi, I hope you're all right. I describe below the scenario where the
problem occurs.
I'm trying to activate a master user [1] to be able to access all the
boxes of all users by imap.
I have configured the dovecot-master-users [2] file with the
appropriate permissions.
When I try to access, for example with roundcube, through
u...@mydomain.com*my_master_u...@not-exist.com
I see in the log, that it seems to ignore the master-user (*) and
tries to authenticate the Active Directory but with the master user's
password. Then it shows in the log the messages
auth: Info: ldap(u...@mydomain.com,127.0.0.1,<6sFGXE6XLwB/AAAB> )
invalid credentials
auth: Debug: client passdb out: FAIL 1 user=u...@mydomain.com
I have other test cases, but I need to validate the master user login that way.
I would appreciate any comments you can make and I am waiting to
answer any questions.
