@cicalese Thanks for your quick response. If the first suggestion is implemented, then I won't bother about changing the button label. I will test it again as soon as the code review is completed and merged to upstream.

I'm not sure whether this is the right place to ask this question. We are running a MediaWiki-1.27 instance with PluggableAuth e and SimpleSAMLphp extensions. Everything works as expected from a technical perspective, but several users have reported usability issues in the login functionality.
