I have a DC Policy "LDAP server signing: Require signing" per GPO. In ExBPA i choose "advanced Login options" (for scheduling ExBPA). After connect to AD Server i get the message: "A more secure authentication method is required for this server" How can i schedule ExBPA with LDAP signing (security requirement in our company)? Without LDAP signing i can connect. regards Dirk

Hi Dirk, What's the version of your exchange server? As far as I know, ExBPA will not request LDAP signing.
