tshark tells me the (smbd) client sends a decrypt error (TLS alert code 
51) to the ldap server after receiving the certificate, while the 
working "ldapsearch -ZZ" moves on to client key exchange etc.

Puzzling, it doesn't seem like a certificate validation error, I'd 
expect that to result in something like codes 42-48.
