2. Authentication Credentials Lists
3. The <Reject /> Verb

When using a multi-tenant system, IP ACL alone won’t
do the trick.
HOW IT WORKS

All requests to the domain require username / password
to authenticate. Identical to HTTP Digest Auth.AUTHENTICATION
Works with IP ACL to accept traffic from multi-tenant
systems. Without IP ACL, allows traffic from any IP.IP ACL INTEGRATION
