Hi, I have dovecot version v2.3.21.1 and my users (username@domain.name) are in mysql, all can logon to imap and sending mail, but when I am trying to create and enable sieve scripts from an weblient (horde webmail) it fails with authentication errors. It tries to use master user authentication and the logs are showing following: A pr 15 10:34:51 auth: Debug: client in: AUTH 1 PLAIN service=sieve secured session=yTdN4nRPFcF/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=4190 rport=49429 resp=aG9yc3QAaG9yc3RAaGJzaW1vbi5uZXQAYXVnQDYmOXVzdA== (previous base64 data may contain sensitive data) Apr 15 10:34:51 auth: Info: plain(horst@hbsimon.net,127.0.0.1,<yTdN4nRPFcF/AAAB>): login user: Master user login attempted without master passdbs Apr 15 10:34:51 auth: Debug: auth(horst@hbsimon.net,127.0.0.1,<yTdN4nRPFcF/AAAB>): Auth request finished Apr 15 10:34:51 auth: Debug: auth client connected (pid=1478) Apr 15 10:34:53 auth: Debug: client passdb out: FAIL 1 user=horst@hbsimon.net Apr 15 10:34:53 managesieve-login: Info: Disconnected: Connection closed (auth failed, 1 attempts in 2 secs): user=<horst@hbsimon.net>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<yTdN4nRPFcF/AAAB> Apr 15 10:35:06 auth: Debug: client in: AUTH 1 PLAIN service=sieve secured session=VEgr43RPGMF/AAAB lip=127.0.0.1 rip=127.0.0.1 lport=4190 rport=49432 resp=aG9yc3QAaG9yc3RAaGJzaW1vbi5uZXQAYXVnQDYmOXVzdA== (previous base64 data may contain sensitive data) Apr 15 10:35:06 auth: Info: plain(horst@hbsimon.net,127.0.0.1,<VEgr43RPGMF/AAAB>): login user: Master user login attempted without master passdbs Apr 15 10:35:06 auth: Debug: auth(horst@hbsimon.net,127.0.0.1,<VEgr43RPGMF/AAAB>): Auth request finished Apr 15 10:35:06 auth: Debug: auth client connected (pid=1484) Apr 15 10:35:08 auth: Debug: client passdb out: FAIL 1 user=horst@hbsimon.net Apr 15 10:35:08 managesieve-login: Info: Disconnected: Connection closed (auth failed, 1 attempts in 2 secs): user=<horst@hbsimon.net>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured, session=<VEgr43RPGMF/AAAB>
How can I bypass the master user login and use the assigned user or what should the master user be and how to create it?
Thanks and Regards, Horst

Hi!
Tell horde not to use master authentication, this should be in the Horde manual.

Hi Unfortunately there is no manual on this. it works perfect if dovecot is using system authentication (pam), but the if using sql authentication. I think it cat not access the users sieve files which are in a directory owned by the virtual master user vmail. When using system pam authentication the users sieve scripts are in its home directory. The horde configuration s is the same for both, I could not see a parameter specifying to use the master user.

if you want to use master login:
passdb master-db { driver = sql query = SELECT password FROM users WHERE userid = '%{user}' and master_user = true master = yes result_success = continue }
see https://doc.dovecot.org/latest/core/config/auth/master_users.html

if horde fails then try roundcube :-)
horde should not use sql for sieve anyway
i have lost horde...
