how to configure use of tls w/ rwm-rewritemap

Hi,

I have a rewrite map configured like:

database ldap suffix "ou=myou" uri "ldap://my.backend/" tls start tls_cacertdir=/my/ca/cert/dir rwm-rewriteMap ldap uid2adminDN "ldap://my.backend/ou=yada,dc=yada?dn?sub" binddn="uid=someone,..." credentials="etc"

My back end is configured to require tls, i.e.

security ssf=128 update_ssf=128 simple_bind=128

If I remove that requirement, everything works. When I add it, my back end ldap server logs:

Jul 1 09:24:28 mid slapd[13011]: conn=1006 op=0 BIND dn="uid=someone,..." method=128 Jul 1 09:24:28 mid slapd[13011]: conn=1006 op=0 RESULT tag=97 err=13 text=confidentiality required

How do I configure rwm-rewritemap to use tls?
