simple bind + X.509 client certificate?

Hi,

using dovecot 2.2.9. The LDAP server requests a client certificate from
dovecot. This client certificate will not be used for authentication,
but anyway, the server requests it. No SASL is involved.
ldapsearch and Exim work as expected, sending the client cert.

The slapd is configured:
    olcTLSVerifyClient: demand

For authentication simple bind should be used.

Dovecot doesn't seem to send the requested client certificate.

If I sniff the connection, the "Certificate" sent to the server is
empty. Using ldapsearch it works (and the certificate isn't empty).

Any suggestions?

    Best regards from Dresden/Germany
