Endpoints (remember, an endpoint is the configuration to use for traffic 
to/from a specific client) can be determined using a pluggable 
mechanism. Included are modules which determine the endpoint based on 
the From header, based on configured IP address matching rules, and 
finally one that just always uses a specific endpoint (used for 
anonymous). Once the endpoint is determined the auth to use is pulled 
from there.
