Sitescope 9.50 and secure LDAP
One of our LDAP servers has been recently upgraded to Windows Server 2016 and that means the old LDAP monitor stopped working, since the server won't accept non-SSL LDAP connections.
I've tried changing the monitor to use "ldaps://" and bind to port 636 instead of just "ldap://", but it fails again and again. Port 636, which is secure LDAP port (correct me if I'm wrong) is open.
Error message reads like this:
Not able to authenticate this user. javax.naming.AuthenticationNotSupportedException (when connecting to "ldap://myserver")
Not able to authenticate this user. javax.naming.ServiceUnavailableException: myserver:636 (when either connecting to "ldaps://myserver" or "ldaps://myserver:636")
Re: Sitescope 9.50 and secure LDAP
This sounds like a TLS version incompatability. I expect LDAPS on Win 2016 would only support the latest or later versions of TLS, and SIS 9.5 is very old so probably only supports older versions of TLS.
