I don't have any idea how to set a higher debug level to dovecot. In my opinion I have the highest. So I can't deliver a greater log.
I recommend consulting Dovecot's advice on how to run a debugger, or dig into the code which calls libldap.
There isn't too much to "debug" in Dovecot's TLS implementation, it's not doing anything fancy asides from calling the ldap_start_tls_s.
I am not sure what debugging you could try further.

This was the answer of the dovecot mailing list. Maybe it would be possible that people from this mailinglist communicate directly with the dovecot mailinglist to find the soulution together and easier.
You may test and debug by means of OpenSSL s_client(1). The starttls and protocol options might provide some insight.

I have found with the dovecot mailinglist the soulution. It was a permission problem because dovecot can't access the *.crt with the rights of a subgroup.
Thanks. Tobias
