Hi all, 
We are doing LDAP search from our Active Directory, the AD enabled "Require signing" option, please see the attachement.  We can't let it work right now. 
I did online google search, LDAP SASL should be the way. But are there any reference or guide to install and configure LDAP SASL?  
Thanks
