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 user@mydomain.com*my_master_user@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(user@mydomain.com,127.0.0.1,<6sFGXE6XLwB/AAAB> ) invalid credentials auth: Debug: client passdb out: FAIL 1 user=user@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.
Regards,
