The server-side sort control is a type of control that can be attached to a search operation to request that the results be sorted before they are returned to the client. It is defined in RFC 2891.

The request control has an OID of 1.2.840.113556.1.4.473 and the value is encoded as follows:

      SortKeyList ::= SEQUENCE OF SEQUENCE {
                 attributeType   AttributeDescription,
                 orderingRule    [0] MatchingRuleId OPTIONAL,
                 reverseOrder    [1] BOOLEAN DEFAULT FALSE } 
The response control has an OID of 1.2.840.113556.1.4.474 and its value is encoded as follows:
      SortResult ::= SEQUENCE {
         sortResult  ENUMERATED {
             success                   (0), -- results are sorted
             operationsError           (1), -- server internal failure
             timeLimitExceeded         (3), -- timelimit reached before
                                            -- sorting was completed
             strongAuthRequired        (8), -- refused to return sorted
                                            -- results via insecure
                                            -- protocol
             adminLimitExceeded       (11), -- too many matching entries
                                            -- for the server to sort
             noSuchAttribute          (16), -- unrecognized attribute
                                            -- type in sort key
             inappropriateMatching    (18), -- unrecognized or
                                            -- inappropriate matching
                                            -- rule in sort key
             insufficientAccessRights (50), -- refused to return sorted
                                            -- results to this client
             busy                     (51), -- too busy to process
             unwillingToPerform       (53), -- unable to sort
             other                    (80)
             },
       attributeType [0] AttributeDescription OPTIONAL }
