3277881 - HTTP header "sap-err-id : ICMLOGONREQUIRED" is received when testing an HTTP connection to an SAP Web Dispatcher


There is a monitoring tool or transaction (possibly provided by a third-party / partner; i.e., non-SAP standard functionality) installed on an ABAP based system.

This monitoring tool requires an HTTP type "G" destination, pointed to the Web Admin UI of an SAP Web Dispatcher.

The aim is to monitor the Web Dispatcher from the ABAP system.

This destination is configured to use "basic authentication" and it has the correct credentials defined.

A "connection test" returns "200 ok". However, the HTTP header "sap-err-id : ICMLOGONREQUIRED" is received (under the "Response Header Fields" tab of the connection test results screen).

The monitoring tool does not work as expected, as a consequence of the apparent authentication failure.
