When running the AA config wizard you encounter the following error even if the SQL details are correct:
An error occurred while attempting to establish a connection to the selected database.
The issue appears to be the initialization of the Wizard page where the username is undefined using Windows Authentication by default. Switching the radio buttons to SQL Authentication and then immediately back corrected the issue by marking the username field as unnecessary to Windows Authentication, which should have been done upon entering the dialog page with Windows Authentication selected.
Defect ID 523219 created to address this in a future version of AA.
Workaround: Select the SQL authentication radio button then click the Windows authentication button, you should be able to progress the wizard.
