All Implemented Interfaces:

org.apache.jackrabbit.api.security.user.UserManager, SessionListener

Direct Known Subclasses:

UserPerWorkspaceUserManager

public class UserManagerImpl
extends ProtectedItemModifier
implements org.apache.jackrabbit.api.security.user.UserManager, SessionListener

Default implementation of the UserManager interface with the following characteristics:

• Users and Groups are stored in the repository as JCR nodes.
• Users are created below UserConstants.USERS_PATH,
  Groups are created below UserConstants.GROUPS_PATH (unless otherwise configured).
• The Id of an authorizable is stored in the jcr:uuid property (md5 hash).
• In order to structure the users and groups tree and avoid creating a flat hierarchy, additional hierarchy nodes of type "rep:AuthorizableFolder" are introduced using
  • the specified intermediate path passed to the create methods
  • or some built-in logic if the intermediate path is missing.

The built-in logic applies the following rules:

• The names of the hierarchy folders is determined from ID of the authorizable to be created, consisting of the leading N chars where N is the relative depth starting from the node at getUsersPath() or getGroupsPath().
• By default 2 levels (depth == 2) are created.
• Parent nodes are expected to consist of folder structure only.
• If the ID contains invalid JCR chars that would prevent the creation of a Node with that name, the names of authorizable node and the intermediate hierarchy nodes are escaped.

Examples: Creating an non-existing user with ID 'aSmith' without specifying an intermediate path would result in the following structure:

 + rep:security            [nt:unstructured]
   + rep:authorizables     [rep:AuthorizableFolder]
     + rep:users           [rep:AuthorizableFolder]
       + a                 [rep:AuthorizableFolder]
         + aS              [rep:AuthorizableFolder]
           + aSmith        [rep:User]
 

Creating a non-existing user with ID 'aSmith' specifying an intermediate path 'some/tree' would result in the following structure:

 + rep:security            [nt:unstructured]
   + rep:authorizables     [rep:AuthorizableFolder]
     + rep:users           [rep:AuthorizableFolder]
       + some              [rep:AuthorizableFolder]
         + tree            [rep:AuthorizableFolder]
           + aSmith        [rep:User]
 

This UserManager is able to handle the following configuration options:

• PARAM_USERS_PATH: Defines where user nodes are created. If missing set to USERS_PATH.
• PARAM_GROUPS_PATH. Defines where group nodes are created. If missing set to GROUPS_PATH.
• PARAM_COMPATIBLE_JR16: If the param is present and its value is true looking up authorizables by ID will use the NodeResolver if not found otherwise.
  If the parameter is missing (or false) users and groups created with a Jackrabbit repository < v2.0 will not be found any more.
  By default this option is disabled.
• PARAM_DEFAULT_DEPTH: Parameter used to change the number of levels that are used by default to store authorizable nodes.
  The value is expected to be a positive integer greater than zero. The default number of levels is 2.
• PARAM_AUTO_EXPAND_TREE: If this parameter is present and its value is true, the trees containing user and group nodes will automatically created additional hierarchy levels if the number of nodes on a given level exceeds the maximal allowed size.
  By default this option is disabled.
• PARAM_AUTO_EXPAND_SIZE: This parameter only takes effect if PARAM_AUTO_EXPAND_TREE is enabled.
  The value is expected to be a positive long greater than zero. The default value is 1000.

PARAM_COMPATIBLE_JR16

public static final String PARAM_COMPATIBLE_JR16

Flag to enable a minimal backwards compatibility with Jackrabbit < v2.0
If the param is present and its value is true looking up authorizables by ID will use the NodeResolver if not found otherwise.

Constant Field Values

PARAM_DEFAULT_DEPTH

public static final String PARAM_DEFAULT_DEPTH

Parameter used to change the number of levels that are used by default store authorizable nodes.
The default number of levels is 2.

NOTE: Changing the default depth once users and groups have been created in the repository will cause inconsistencies, due to the fact that the resolution of ID to an authorizable relies on the structure defined by the default depth.
It is recommended to remove all authorizable nodes that will not be reachable any more, before this config option is changed.

• If default depth is increased:
  All authorizables on levels < default depth are not reachable any more.
• If default depth is decreased:
  All authorizables on levels > default depth aren't reachable any more unless the PARAM_AUTO_EXPAND_TREE flag is set to true.

See Also:

Constant Field Values

PARAM_AUTO_EXPAND_TREE
