Is there anyone know how to understand geoserver security?
The version of geoserver i used is 2.1.0,when i look up the "Layer-level security",there are several examples:
althought there is one paragraph to explain the permissions as follows:
Each entry must have a unique combination of namespace, layer, and permission values. If a permission at the global level is not specified, global permissions are assumed to allow read/write access. If a permission for a namespace is not specified, it inherits permissions from the global specification. If a permission for a layer is not specified, it inherits permissions from its namespace specification. If a user belongs to multiple roles, the least restrictive permission they inherit will apply.
