Rolling back the chages made to a web application, regarding to claim-based authentication...

Hi all;

Suppose I have incorrectly executed the following PowerShell command:

$map = New-SPClaimTypeMapping -IncomingClaimType "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn" IncomingClaimTypeDisplayName "UPN" -SameAsIncoming

Now when I want to identify the users in that web application, I encounter the following problem:

The problem above is due to missing the "-" character before theIncomingClaimTypeDisplayNamesyntax. Now how can I resolve the problem?

Thanks
