UNCUserName

  • Article

The UNCUserName property specifies the user name for Universal Naming Convention (UNC) virtual roots. Use this property only as a flag for authentication schemes that support delegation.

Note

Integrated Windows authentication (NTLM) does not support delegation.

When a request comes in to the IIS server, IIS looks at the UNCUserName property on the virtual directory. If the property exists and it is not an empty string, then the UNC user name and password are used for authentication. If authentication fails, a 401.2 error is returned to the client. If authentication passes, then the client's original credentials are passed through to the resources that were requested.
