[Juser] Openldap authentication question

[Alejandro Cabrera Obed]

Dear people, I've setup a Jabberd2 server with MySQL storage and
Openldap authentication.
If I use clients like PSI authenticating in clear text I succeed in my
login. But now I want to setup encrypted authentication between client
and jabberd.
My questions are:

1) Should I have to establish any addditional setting for STARTTLS in
Openldap ???

2) Which jabber client allow STARTTLS connection setting ???

Thanks a lot,

alejandro
