As @guardiande mentions in #1526 auth_bind is needed for some setups. Setting a default of no, so it doesn't break the existing setup. But by having the value in the dovecot-ldap.conf.ext it should be overridable with a env variable like DOVECOT_AUTH_BIND.

Is this PR work in progress? You mention an env variable, but it is not there?

From start-mailserver.sh

configomat.sh "DOVECOT_" "/etc/dovecot/dovecot-ldap.conf.ext"

So creating the container with (that's the variable you're missing, it's not part of the PR 😊)

environment:
      - DOVECOT_AUTH_BIND=yes

would allow for closing #1526

Ah, ok. I misunderstood. I didn't think we had to specify all environment variables up front, only if you needed it used in the container. So I didn't add this to the env file, so it would retain the current default behavior.

But I can update the env file to include it.

No, you don't have to include the variable in the env file. You did everything right. Only if someone - like me - wants to have auth_bind set to yes she would have to override the default setting (which is no) to yes by including the DOVECOT_AUTH_BIND variable set to yes in the environment.

Ya, I noticed there were a few other DOVECOT_ variables that could be used, but were not specified (DOVECOT_USER_ATTRS, DOVECOT_PASS_ATTRS, and DOVECOT_DEFAULT_PASS_SCHEME). But since the AUTH_BIND wasn't defined in the dovecot ldap.conf, it couldn't be overridden with environment variable.

I just committed another change to add DOVECOT_AUTH_BIND to the env file, so if @erik-wramner wants to review now, I think this can be pulled.
