During SCIM sync project creation, the test connection fails and a third party network traffic capture tool (e.g. wireshark) shows that there is no traffic being sent to the service provider with the following setting:
1. Using "Basic Authentication" with empty "Authentication Endpoint/URL" field, because the target system does not provide a specific authentication endpoint.
2. However, entering any value (e.g. just a '/' character) for "Authentication Endpoint/URL", the connection test succeeds and network trace shows traffic.
Development has acknowledged change request #32627 and fixed as part of the 8.1.2 SP release.
