Class GetEffectiveRightsRequestControl

    java.io.Serializable

    public final class GetEffectiveRightsRequestControl
    extends Control
    This class provides an implementation of the get effective rights request control, which may be included in a search request to indicate that matching entries should include information about the rights a given user may have when interacting with that entry.
    NOTE: This class, and other classes within the com.unboundid.ldap.sdk.unboundidds package structure, are only supported for use against Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 server products. These classes provide support for proprietary functionality or for external specifications that are not considered stable or mature enough to be guaranteed to work in an interoperable way with other types of LDAP servers.

    When the get effective rights control is included in a search request, then each entry returned may include information about the rights that the specified user has for that entry in the aclRights operational attribute. Note that because this is an operational attribute, it must be explicitly included in the set of attributes to return.

    If the aclRights attribute is included in the entry, then it will be present with multiple sets of options. In one case, it will have an option of "entryLevel", which provides information about the rights that the user has for the entry in general (see the EntryRight enum for a list of the entry-level rights that can be held). In all other cases, it will have one option of "attributeLevel" and another option that is the name of the attribute for which the set of rights is granted (see the AttributeRight enum for a list of the attribute-level rights that can be held). In either case, the value will be a comma-delimited list of right strings, where each right string is the name of the right followed by a colon and a one to indicate that the right is granted or zero to indicate that it is not granted. The EffectiveRightsEntry class provides a simple means of accessing the information encoded in the values of the aclRights attribute.

    This control was designed by Sun Microsystems, and it is not the same as the get effective rights control referenced in the draft-ietf-ldapext-acl-model Internet draft. The value for this control should be encoded as follows:

     GET_EFFECTIVE_RIGHTS := SEQUENCE {
       authzID     authzID,
       attributes  SEQUENCE OF AttributeType OPTIONAL }
     

    Example

    The following example demonstrates the use of the get effective rights control to determine whether user "uid=admin,dc=example,dc=com" has the ability to change the password for the user with uid "john.doe":
     SearchRequest searchRequest = new SearchRequest("dc=example,dc=com",
          SearchScope.SUB, Filter.createEqualityFilter("uid", "john.doe"),
          "userPassword", "aclRights");
     searchRequest.addControl(new GetEffectiveRightsRequestControl(
          "dn:uid=admin,dc=example,dc=com"));
     SearchResult searchResult = connection.search(searchRequest);
    
     for (SearchResultEntry entry : searchResult.getSearchEntries())
     {
       EffectiveRightsEntry effectiveRightsEntry =
            new EffectiveRightsEntry(entry);
       if (effectiveRightsEntry.rightsInformationAvailable())
       {
         if (effectiveRightsEntry.hasAttributeRight(AttributeRight.WRITE,
              "userPassword"))
         {
           // The admin user has permission to change the target user's password.
         }
         else
         {
           // The admin user does not have permission to change the target user's
           // password.
         }
       }
       else
       {
         // No effective rights information was returned.
       }
     }
