This class defines the XrdSecEntity object post processing plugin. When authentication succeeds, the plugin is called to inspect and possible decorate (e.g. add attributes) the entity object. The plugin also has the capability of returning failure due to some problem. When failure ooccurs, the security framework moves on to another authentication protocol, if one is avalable. Entity post processing plugins may be stacked. You always return the results of the stacked plugin whether or not you wish to handle the entity object, if a stacked plugin exists; unless you return false.
