[Live-devel] Slight authentication change

Yes.  In fact, I can think of another way to do this that's even 
simpler, yet more general:

Add a new member function
	UserAuthenticationDatabase* 
RTSPServer::setAuthenticationDatabase(UserAuthenticationDatabase* 
newDB);
This would change the server's authentication database, and return 
the existing one (perhaps NULL).

Then, you could turn off authentication simply by doing:
	UserAuthenticationDatabase* oldDB = 
myServer->setAuthenticationDatabase(NULL);
and turn it back on by doing:
	myServer->setAuthenticationDatabase(oldDB);
This also has the benefit of not requiring an additional check in the 
server; the existing check against NULL is sufficient.
