Scenario:

• A user runs an FBA-authenticating Ideagen Internal Audit (Aura) client from the server, and is able to log in successfully
• They take the same client package and run it from a client PC, but get the message "Login Failed"

Assuming the password is being entered correctly (and caps lock is off), the cause is almost certainly a problem with the system's SSL configuration.  As an FBA client connects to the service via SSL and is unable to display an error message, all that will be seen is a standard failure message.

To troubleshoot further, browse to the service URL ensuring an https connection, e.g.:

  https://servername/instancename/Service/TngService.svc

The error that comes back can help determine the cause, e.g. missing bindings, an expired or untrusted certificate.
