----------------------------------------------------
h4. 1. Characteristics of the Default Implementation
h5. General
h5. JCR API
h6. AccessControlManager#hasPrivilege and #getPrivileges
As of OAK those methods throw {{PathNotFoundException}} if the corresponding
node is not accessible by the editing session. This is in accordance with the
behavior mandated by JSR 283 and a bug in Jackrabbit 2.x.
h6. AccessControlManager#getEffectivePolicies
In contrast to Jackrabbit 2.x the editing session is used to retrieve the
effective policies and the policies returned by these methods are guarantueed
to only return information that is otherwise accessible by the session. The
corresponding methods in Jackrabbit 2.x use to throw an exception in this
situation.
h5. Jackrabbit API
h6. Principal-based Access Control
The principal-based access control management as present in Jackrabbit-core is
no longer present with OAK. The main benefit of the principal-based approach
has been incorporated with the changes in the default permission evaluation
(see OAK-942). In addition the default access control manager implementation
supports all methods defined by {{JackrabbitAccessControlManager}}; i.e.
editing access control information by principal is possible as long as the
editing session has sufficient permission on the target node(s). Similarly, the
per principal policies exposed to a given session will always respect that
access rights of that session.
h6. Restrictions
The implementation of the additional restrictions associated with an ACE has
been modified/extended as follows:
* Separate restriction management API (see below) on the OAK level that allows
to ease plugging custom restrictions.
* Changed node type definition for storing restrictions in the default
implementation.
** as of OAK restrictions are collected underneath a separate child node
"rep:restrictions"
** restrictions can be multi-valued (see JCR-3637)
** backwards compatible behavior for restrictions stored underneath the ACE
node directly
* New restriction "rep:ntNames", which allows to limit the affect ACE to nodes
of the specified node type(s)
h4. 2. Node Types
As mentioned above the node type definitions have been extended to match the
new functionality related to restrictions.
The node type definition for access control entries:
{code}
[rep:ACE]
- rep:principalName (STRING) protected mandatory
- rep:privileges (NAME) protected mandatory multiple
- rep:nodePath (PATH) protected /* deprecated in favor of restrictions */
- rep:glob (STRING) protected /* deprecated in favor of restrictions */
- * (UNDEFINED) protected /* deprecated in favor of restrictions */
+ rep:restrictions (rep:Restrictions) = rep:Restrictions protected
{code}
The new node type definition for restrictions:
{code}
/**
* @since oak 1.0
*/
[rep:Restrictions]
- * (UNDEFINED) protected
- * (UNDEFINED) protected multiple
{code}
h4. 3. API Extensions and Public Classes
org.apache.jackrabbit.oak.spi.security.authorization.accesscontrol
- {{AbstractAccessControlList}}
- {{ImmutableACL}}
- {{ACE}}
org.apache.jackrabbit.oak.spi.security.authorization.restriction

{{AuthorizationConfiguration}} as of OAK 1.0
