After an upgrade to Exchange 2010 SP1, to add the update rollup 3 (v3), OWA stopped logging users in, instead just leaving them on a blank page (This was really a HTTP 500 error page for auth.owa).

Turns out that the “Microsoft Exchange Forms-Based Authentication service” was not restarted after the patching. Starting the service fixes this issue.
