| # The SASL layer is responsible for establishing an authenticated and/or |
| # encrypted tunnel over which AMQP frames are passed between peers. |
| # |
| # The peer acting as the SASL client must provide authentication |
| # credentials. |
| # |
| # The peer acting as the SASL server must provide authentication against the |
| # received credentials. |
| # |
| # @example |
| # # SCENARIO: the remote endpoint has not initialized their connection |
| # # then the local endpoint, acting as a SASL server, decides |
| # # to allow an anonymous connection. |
| # # |
| # # The SASL layer locally assumes the role of server and then |
| # # enables anonymous authentication for the remote endpoint. |
