Yes, this is normal protocol behavior. I presume you’re running the “LIVE555
Proxy Server” with the
-u <username> <password>
command-line option, to tell it the username and password of the back-end
camera.

If you’re using the correct username/password, then this seems like a problem
(bug) with the back-end camera.
But, to be sure, please post an example of the diagnostic output from the
"LIVE555 Proxy Server” - i.e., if you give it the
-V
option (as well as "-u <username> <password>”, of course).
