 ### Proxy Roles
 
-By default, the broker treats the connection between a proxy and the broker as a normal user connection. The broker authenticates the user as the role configured in `proxy.conf`(see ["Enabling TLS Authentication on Proxies"](security-tls-authentication#on-proxies)). However, when the user connects to the cluster through a proxy, the user rarely requires the authentication. The user expects to be able to interact with the cluster as the role for which they have authenticated with the proxy.

 Pulsar uses *Proxy roles* to enable the authentication. Proxy roles are specified in the broker configuration file, [`conf/broker.conf`](reference-configuration.md#broker). If a client that is authenticated with a broker is one of its ```proxyRoles```, all requests from that client must also carry information about the role of the client that is authenticated with the proxy. This information is called the *original principle*. If the *original principle* misses, the client is not able to access anything.
