When a user receives a block page and is presented with the option to log in as a different user, we wish to change the time value that the WSA stores those credentials. Right now it's 5 minutes and we'd like it to be 30. It looked like ~4 different fields were related to this, but we weren't sure which one was the correct value we need to change.
It doesn't appear to be the Basic Authentication Token TTL or Credential Cache Options, becuase those are set to 3600 seconds, and it still starts blocking users again after 5 minutes.
