I'm using LDAP with Okta as, and I can't even pass through the authentication either.
We used Okta certs.
The tests fail every time, but I can connect using LDAP directly on port 636 with a Client(and I have a similar setup on my Printing service and it works with no issues). But if I attempt to do it with Meraki is no communication whatsoever. If I try to connect to the test ssid i get fail authentication every time...
I really want this feature to works but I'm having a hard time with it.
