public class LdapSortResponseControl extends netscape.ldap.controls.LDAPSortControl implements Control
The LDAP server sends back a sort response control to indicate the result of the sorting operation. (The OID for this control is 1.2.840.113556.1.4.474.)

This control contains:

  • the result code from the sorting operation
  • optionally, the first attribute type in the sort key list that resulted in an error (for example, if the attribute does not exist)

To parse this control, use the parseResponse method.

The following table lists what kinds of results to expect from the LDAP server under different situations:
