Hello,

I have Director setup to proxy requests to backend servers. This works fine when using "standard" username/passwords.

I am not try to enable the use of the Dovecot Master user through Director into the backend servers.

a.) username is being sent as masteruser*username

b.) request hits the proxy and authenticates, and then is passed to the backend servers and fails auth.

- logs from proxy/Director point of view.

auth: Info: passwd-file(masteruser,172.31.33.224,master,<z2eYD0Rl6P+sHyHg>): Master user logging in as devteam

imap-login: Info: proxy(devteam): Login failed to backend.servers:143 (master masteruser): [AUTHENTICATIONFAILED] Authentication failed.: user=<devteam>, method=PLAIN, rip=172.31.33.224, lip=192.168.71.20, session=<z2eYD0R

l6P+sHyHg>

- logs from backend server point of view.

imap-login: Info: Disconnected (auth failed, 1 attempts in 2 secs): user=<masterusername>, method=PLAIN, rip=192.168.71.20, lip=192.168.71.99, session=<O8QN8kNlloXAqEcU>

Proxy/Director Configs (hopefully this is enough)

auth_master_user_separator = *

passdb {

driver = passwd-file

args = /etc/dovecot/conf.d/master-user-password

master = yes

pass = yes

}

passdb {

driver = static

args = proxy=y nopassword=y

}

Please let me know if I can provide any further details.

Thanks in advance.
