    Direct Known Subclasses:

    public class AccessMgrImpl
extends Manageable
implements AccessMgr, Serializable
    Implementation class that performs runtime access control operations on data objects of type Fortress entities This class performs runtime access control operations on objects that are provisioned RBAC entities that reside in LDAP directory. These APIs map directly to similar named APIs specified by ANSI and NIST RBAC system functions. Many of the java doc function descriptions found below were taken directly from ANSI INCITS 359-2004. The RBAC Functional specification describes administrative operations for the creation and maintenance of RBAC element sets and relations; administrative review functions for performing administrative queries; and system functions for creating and managing RBAC attributes on user sessions and making access control decisions.

    RBAC0 - Core

    Many-to-many relationship between Users, Roles and Permissions. Selective role activation into sessions. API to add, update, delete identity data and perform identity and access control decisions during runtime operations.

    RBAC1 - General Hierarchical Roles

    Simplifies role engineering tasks using inheritance of one or more parent roles.

    RBAC2 - Static Separation of Duty (SSD) Relations

    Enforce mutual membership exclusions across role assignments. Facilitate dual control policies by restricting which roles may be assigned to users in combination. SSD provide added granularity for authorization limits which help enterprises meet strict compliance regulations.

    RBAC3 - Dynamic Separation of Duty (DSD) Relations

    Control allowed role combinations to be activated within an RBAC session. DSD policies fine tune role policies that facilitate authorization dual control and two man policy restrictions during runtime security checks.

    This class is NOT thread safe if parent instance variables (Manageable.contextId or Manageable.adminSess) are set.

      • authenticate

        public Session authenticate​(String userId,
                            String password)
                     throws SecurityException
        Perform user authentication only. It does not activate RBAC roles in session but will evaluate password policies.
        Specified by:
        authenticate in interface AccessMgr
        Parameters:
        userId - Contains the userid of the user signing on.
        password - Contains the user's password.
        Returns:
        Session object will be returned if authentication successful. This will not contain user's roles.
        Throws:
        SecurityException - in the event of data validation failure, security policy violation or DAO error.

      • checkAccess

        public boolean checkAccess​(Session session,
                           Permission perm)
                    throws SecurityException
        Perform user RBAC authorization. This function returns a Boolean value meaning whether the subject of a given session is allowed or not to perform a given operation on a given object. The function is valid if and only if the session is a valid Fortress session, the object is a member of the OBJS data set, and the operation is a member of the OPS data set. The session's subject has the permission to perform the operation on that object if and only if that permission is assigned to (at least) one of the session's active roles. This implementation will verify the roles or userId correspond to the subject's active roles are registered in the object's access control list.
        Specified by:
        checkAccess in interface AccessMgr
        Parameters:
        session - This object must be instantiated by calling AccessMgr.createSession(org.apache.directory.fortress.core.model.User, boolean) method before passing into the method. No variables need to be set by client after returned from createSession.
        perm - must contain the object, Permission.objName, and operation, Permission.opName, of permission User is trying to access.
        Returns:
        True if user has access, false otherwise.
        Throws:
        SecurityException - in the event of data validation failure, security policy violation or DAO error.

      • checkAccess

        public boolean checkAccess​(User user,

                    throws SecurityException
        Combine createSession and checkAccess into a single method. This function returns a Boolean value meaning whether the User is allowed or not to perform a given operation on a given object. The function is valid if and only if the user is a valid Fortress user, the object is a member of the OBJS data set, and the operation is a member of the OPS data set. The user has the permission to perform the operation on that object if and only if that permission is assigned to (at least) one of the session's active roles. This implementation will verify the roles or userId correspond to the user's active roles are registered in the object's access control list.

        checkAccess in interface AccessMgr
        Parameters:
        user - Contains User.userId, User.password (optional if isTrusted is 'true'), optional User.roles}
        perm - must contain the object, Permission.objName, and operation, Permission.opName, of permission User is trying to access.
        Returns:
        True if user has access, false otherwise.
        Throws:
        SecurityException - in the event of data validation failure, security policy violation or DAO error.
