Description (partial)

- The XTC/PCE server is configured on the XR device (cXR/eXR).
- REST API is configured with "authentication basic" along with local username/password for the REST API users.

- This is a day-1 issue and affects all XR platforms (cXR and eXR). This is platform independent issue.
- XR 6.3.3+ onwards are potentially affected releases but it may also affect earlier releases too.


- The "debug pce rest" and "debug pce rest api" are configured on the device. 
- We see that after the REST client initiates the session with incorrect user/pass the following debugs are observed:
