In response to: LDAP Sort Control -- RFC 2891
Posted on: 06/07/2007 12:47:50 PM
This control is included in the searchResultDone message as part of
the controls field of the LDAPMessage, as defined in Section 4.1.12
of [LDAPv3].
The controlType is set to 1.2.840.113556.1.4.474. The criticality
is FALSE (MAY be absent). The controlValue is an OCTET STRING, whose
value is the BER encoding of a value of the following SEQUENCE:
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 }

Request Control
This control is included in the searchRequest message as part of the
controls field of the LDAPMessage, as defined in Section 4.1.12 of
[LDAPv3].
The controlType is set to 1.2.840.113556.1.4.473. The criticality
MAY be either TRUE or FALSE (where absent is also equivalent to
FALSE) at the client's option. The controlValue is an OCTET STRING,
whose value is the BER encoding of a value of the following SEQUENCE:
SortKeyList ::= SEQUENCE OF SEQUENCE {
attributeType AttributeDescription,
orderingRule [0] MatchingRuleId OPTIONAL,
reverseOrder [1] BOOLEAN DEFAULT FALSE }
The SortKeyList sequence is in order of highest to lowest sort key
precedence.
The MatchingRuleId, as defined in section 4.1.9 of [LDAPv3], SHOULD
be one that is valid for the attribute type it applies to. If it is
not, the server will return inappropriateMatching.
Each attributeType should only occur in the SortKeyList once. If an
attributeType is included in the sort key list multiple times, the
server should return an error in the sortResult of
unwillingToPerform.
If the orderingRule is omitted, the ordering MatchingRule defined for
use with this attribute MUST be used.
Any conformant implementation of this control MUST allow a sort key
list with at least one key.
