Netscape with TLS and userlogin

[Dennis Berger <Dennis.Berger@nipsi.de>]

I have slapd configured that only users logged in have read access.
I can perform searches on my ldaptree and autocompletion works fine, but
if I doubleclick on a contact nothing happens this is because the
composer calls the netscape with the following URL
"ldaps://ldap.nipsi.de%20..." but netscape navigator doesn't know what
to do with ldaps and nothing happens. If I switch ssl off, everything
work correctly cause the composer calls netscape with a URL similar to
this ldap://ldap.nipsi.de%20 ... and netscape knows about "ldap://";, but
not "ldaps://"
How could I get my addressbook to work properly with ssl support ?
