Cookie (BIG-IPAuthCookie) based authentication is no longer supported for iControl REST API to prevent CSRF security vulnerability. But when a logon fails the authentication, there is no basic auth challenge (WWW-Authenticate header) in the response.
Because of the missing Basic Auth challenge, browser/soapUI/Postman tools cannot use cached user credentials.
Issue happens with cookie (BIG-IPAuthCookie) based authentication.
Workaround is to remove the cookie (BIG-IPAuthCookie) from browser session so it does not get included in the sent request.
This release now includes a Basic Auth challenge (WWW-Authenticate header) in 401 F5 Authorization Required responses.
