You send a request to a resource and the service responds with HTTP status code 401 (Unauthorized).

This usually occurs for one of two reasons:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

	<html>

	<head>

	<title>Error</title></head>

	<body text="#000000">

	<h1>Error 401</h1>You are not authorized to perform this operation</body>

	</html>
  • You are sending an anonymous request (no user credentials) to a protected resource. In this case, you can correct the problem by supplying the appropriate user credentials with each request.

See the appropriate.Domino web server documentation for more about these authentication schemes.
  • The authenticated user has insufficient access to the resource. In this case, you can correct the problem by changing the access control list (ACL) for the database. A response body in HTML format usually accompanies an HTTP status code of 401. The response body may help you troubleshoot the error. For example:
