If you have Integrated Windows Authentication as the only authentication type enabled in VisualSVN Server you don't get any login / password prompts.
You may find yourself stuck and confused if sometimes you should access VisualSVN Server under other users' account than the one you are currently logged-on.
Is there any convenient workaround?
You can use the Windows Credential Manager to store the other account's credentials for Single Sign-On.
The following instruction shows how to put other domain credentials to access VisualSVN Server into Windows Credential Manager:
Start | Control Panel | Credential Manager,
Click 'Add a Windows Credential',

Verify that you can authenticate to VisualSVN Server under the selected user account after completing the above steps.
