Version Affected: All
Several strange issues can occur when signing into a Realm. For example, the Submit button appears to do nothing for but hitting it several times works.
Or, after selecting a second factor method, you end up back at the Username prompt again.
Incorrect AppPool Worker process settings means the Session cookie doesn't always match the worker process so the login attempt has to start again.
1. Open IIS
2. Navigate to the AppPool section
3. Open up the AppPool (Normally .Net 4.5) Advanced Settings
4. Make sure the Maximum Worker Processes is set to 1
If you wish to spread the load across more CPU, instead of increasing the Max Worker Processes, simply add an extra AppPool and move some of your realms to that AppPool. Just make sure the settings are exactly the same.
