/**
|
|
* Authentication mechanism
|
|
*
|
|
* An authentication mechanism can have services injected during construction,
|
|
* such as \OCP\IDB for database operations. This allows an authentication
|
|
* mechanism to perform advanced operations based on provided information.
|
|
*
|
|
* An authenication scheme defines the parameter interface, common to the
|
|
* storage implementation, the backend and the authentication mechanism.
|
|
* A storage implementation expects parameters according to the authentication
|
|
* scheme, which are provided from the authentication mechanism.
|
|
*
|
|
* This class uses the following traits:
|
|
* - VisibilityTrait
|
|
* Restrict usage to admin-only/none
|
|
* - FrontendDefinitionTrait
|
|
* Specify configuration parameters and other definitions
|
|
* - StorageModifierTrait
|
|
* Object can affect storage mounting
