openldap and dadlauthd

Hi,

I have problems to get saslauthd to work with my openldap server:

- saslauthd binds/autneticates if I connect to the non SSL port ldap://ldap.cs.ait.ac.th/

- saslauthd fails to bind/autneticate if I connect to the SSL port ldaps://ldap.cs.ait.ac.th/

Jul 23 12:02:00 ldap slapd[41289]: conn=22 fd=19 ACCEPT from IP=192.41.170.50:62502 (IP=192.41.170.6:636) Jul 23 12:02:00 ldap slapd[41289]: connection_closing: readying conn=22 sd=19 for close Jul 23 12:02:00 ldap slapd[41289]: connection_close: conn=22 sd=-1 Jul 23 12:02:00 ldap slapd[41289]: conn=22 fd=19 closed (TLS negotiation failure)

I really don't know where to look.

TIA,

Olivier
