Issue with NameID Format field

I don't get the same behavior (unless when entering urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress as value). Also, "Email address" is not the default value.

So, offhand, I can think of two possibilities:

• The config value urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress is set through your settings.php somewhere
• The value you have been repeatedly trying to enter, was always urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress. This is the pretty-much-official-standard machine name for an email address, so that value shows as "Email address" in the dropdown (while being saved as urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress).

If it's neither of these: sorry, I don't know other questions to ask.

If it's the second point: I realize this is not explicitly spelled out in the UI, but I was kinda hoping it would be implicitly clear that the 'machine name' translates to the 'homan name' that shows up... to whoever tries it, so the values in the dropdown don't have to be super long...
