I know the are other questions similar to this one, but I haven't found one that is the same.
Here's the thing: I've successfully configured a web app in SharePoint to authenticate using ADFS. When I open the people picker, I can see my claims provider and the claim (Email Address). The problem is that I can search anything and the people picker will tell me that whatever I look for belongs to the claim provider.
For example: I have a user named steve.harris and the email firstname.lastname@example.org. When I search in the people picker for 'steve', It will appear as if 'steve' was the e-mail. And I can even search for 'foo' and grant it permissions and people picker won't complain about 'foo' not existing anywhere.
Any ideas? Thanks.
