Bind to ldap using encryption

I have just installed openfire for the first time (replacing an old install of Jabber2). In order to authenticate against ldap I had to remove ssf=112 from my slapd acl. Changed

access to attr=userPassword
by ssf=112 anonymous auth
by ssf=128 self write
by * none

to

access to attr=userPassword
by anonymous auth
by ssf=128 self write
by * none

Is there a setting I can add to openfire to allow me to bind with ssf=112 in place again? I would like to leave the same security on ldap since there are many other systems that authenticate against this (note: jabber2 worked with this just fine)
