Support » Plugin: Active Directory Integration » Authentication failed… but why?

  • I’ve seen similar posts but there don’t seem to be any answers. According to the plugin description “It is very easy to set up. Just activate the plugin, type in a domain controller, and you’re done.” I tried that but no dice.

    The only [ERROR] is that authentication failed, but I don’t know why. Is there any more information I can get from this test tool? Or does anyone have any suggestions?

    Things I’ve tried
    – enable/disable TLS
    – port 636 (although the response shows port 389 was good)
    – prepending domain name i.i “domain\”
    – including a suffix (which we don’t even use)

    Any hints as to WHY authentication is failing?
