Getting prompted to log into TFS server when connecting to a database that uses TFS for version c (4241950)

When I log into a database that is using TFS for version control, I am prompted to log into the TFS server. This should automatically be done using OS authentication. Why am I getting prompted?

WORKAROUND:
Launch:
Control Panel\All Control Panel Items\Credential Manager\Add a Windows Credential

Put in the IP of the TFS server along with the Windows user credentials in the form
DOMAIN\username
password

STATUS:
Waiting for fixt to be released in a future version of Toad for Oracle.
