It is important to note that the domain name (BLACKBAUDHOST\) does not need to be included when entering the username into the app. However, if this still does not resolve the issue, then you may need to disable Windows Authentication

To do this, login to the Raiser's Edge and then:
  1. Navigate to admin>security
  2. Double click the username
  3. Unmark the box for windows authentication
  4. Ensure that the RE7 authentication box is marked and take note of the credentials
  5. Save and Close
  6. Login to the Event Management App using the RE7 crednetials

For some organizations, a specific RE user account is created for each device that the application is installed on. This allows for a specific login for each device and does not require that windows authentication be disabled for a specific user to login to the app.
