Context

In order to use this container with my LDAP server, I have to use TLS with SASLauth and Dovecot. Unfortunately, I don't see any envvar that would allow me to set the desired options.

Expected Behavior

- SASLAUTHD_LDAP_START_TLS=yes set ldap_start_tls: yes in /etc/saslauthd.conf
- SASLAUTHD_LDAP_TLS_CHECK_PEER=no set ldap_tls_check_peer: no in /etc/saslauthd.conf
- DOVECOT_TLS_REQUIRE_CERT=never set tls_require_cert = never in /etc/dovecot/dovecot-ldap.conf.ext

Generally, I would like to be able to use more ldap envvars without mounting a file in the container (I'm using Kubernetes and it's not very practical), like those :

Possible Fix

Add more envvars to configure LDAP for dovecot and salsauth.
