Hi,
I'm using dovecot 2.2.9 (but after checking src/auth/db-ldap.c in 2.2.13 there seems to be the same bug/feature).
The userdb and passdb use LDAP. All further configuration is done in auth-ldap.conf.ext.
uri = ldaps://<host>/ # tls = tls_cert_file = /etc/ssl/certs/client-cert.pem tls_key_file = /etc/ssl/certs/client-key.file
Dovecot ignores the tls_* options. If I use an ldap:// URI and switch on TLS using tls=yes it works as expected.
But I do not see any reason why LDAPS should not read the tls_* settings.
I guess.
This small patch solved it for me

That's a bit ugly. I think also the URIs support multiple ones, so some ldap and some ldaps URLs could even be mixed, which of course would be quite ugly.. I think the fix is to just remove the if (tls)-check completely. I don't think setting those harms anything even if tls/ldaps isn't being used?
