Problem implementing smart card authentication (4344608)

After trying to enable smart card authentication, I am unable to login so that I can change back to forms based authentication.

Work Around:

1. Using SQL management studio, connect to your SQL server and expand your Change Auditor database.
2. Expand tables and find the dbo.SystemProperty table
3. Right-click on dbo.SystemProperty and select "Edit top 200 rows"
4. In the right-hand pane, you should see the query results open up
5. Look for the PropKey with the value of "AuthenticationOptions"
6. Click on the PropValue to the right of that PropKey and change the value to be 8
7. Click on any other cell to commit the change to the database
8. Restart the coordinator service

Once the coordinator service is in a running state, you should be able to connect via the client again.
