Frankly, no I didn't :-(
I just misinterpreted RFC2459 which says a name has to be a

Thanks to your remarks, I now changed my certificate, which now shows

dieter@marin:/usr/local/bin> ./ldapwhoami -Y EXTERNAL -ZZ
SASL/EXTERNAL authentication started
SASL username: CN=Dieter Kluenter,OU=partner,O=avci,C=de
dn:cn=dieter kluenter,ou=partner,o=avci,c=de

and best of all, I don't need a mapping to my entry by means of
