IWP being flaky with External Authentication

[dmeyer]

I have a FMS9a solution that has been authenticating IWP users against Active Directory. It has been working fine until the last few days. Suddenly now, it will occasionally refuse to authenticate users. Enter valid credentials and it just refreshes back to the login screen.

Then, I'll quit the browser, reload the page, and it'll work fine.

Then log out of IWP, restart browser, and it will fail.

Not having any issues when accessing via FMAPP.

Any ideas? Of course the logs arent saying anything other than authentication failed.

Check to be sure that the server hosting FileMaker Server is correctly bound to the AD domain.
