The LDAP server requires at least SSL or TLS to establish the connection. Usually this issue is the result of a domain policy set in active directory that enforces all LDAP authentication to be secured with SSL. The policy on the domain controller is: "Domain controller: LDAP server signing requirements" and if set to "Require signing" the LDAP data-signing option must be negotiated unless Transport Layer Security/Secure Socket Layer (TLS/SSL) is being used.
If this policy is configured on one's domain controllers in a Windows Domain, non-secure LDAP authentication will fail. -- -jim Jim Willeke On Thu, Nov 22, 2012 at 1:48 AM, 杨华杰 <[email protected]> wrote: > DSID-0C0901FC
