You should *either* use an ldaps:/// URI (for ldaps), or use an ldap:/// URI
with 'ssl start_tls'. While you may have a working client configuration
(probably trying ldaps), you'll probably confuse someone ....

You are only listening on ldaps, so unless you change your -h argument, you
can't do START_TLS.

So, you have just tried to do a START_TLS bind on the ldaps port, which is
obviously not how things are supposed to work. Either use -H
ldaps:///my.server.tld without -Z, or -H ldap://my.server.tld or -h
my.server.tld *with -Z.
Please note that ldaps (usually port 636) is different to START_TLS, you can't
use both, you can not do START_TLS on the ldaps port, and you can't do ldaps
on the normal ldap port (which is where you do START_TLS).
Since your slapd is only listening on ldaps, you should probably try with -H
ldaps://my.server.tld (no -Z).
