Hi everybody,
thank you all for your immediate replies.
As you correctly pointed out, the options I used were wrong. With following ldap.conf, everything works out fine.
base dc=... URI ldaps://<fqdn of ldap server>/ ldap_version 3 rootbinddn cn=... bind_policy soft pam_password md5
TLS_REQCERT yes TLS_CACERT /usr/lib/ssl/certs/<ca>.chain.crt
The ldap.conf I used before has been created by dpkg-reconfigure and I simply changed the default values there. That was a mistake ;-) Creating a new ldap.conf from scratch with a man-page at hand obviously did the trick.
Thank you very much for your help,
Best regards,
Hauke

You cannot use StartTLS (ldapsearch -Z) with an ldaps:// server, it's redundant.

The above 3 keywords are not valid for ldap.conf. Read the ldap.conf(5) manpage.
