LDAPWiki: Modify Request

Overview#

ModifyRequest is a LDAP Message used to update an existing LDAP Entry in the DIT.

The modify request LDAP Message is defined in RFC 4511 as follows:

ModifyRequest ::= [APPLICATION 6] SEQUENCE 
{
    object          LDAPDN,
    changes         SEQUENCE OF change SEQUENCE 
    {
        operation       ENUMERATED 
        {
            add     (0),
            delete  (1),
            replace (2),
            ...  
        },
        modification    PartialAttribute 
    } 
}

Fields of the Modify Request are:#

object - The value of this field contains the DistinguishedName (DN) of the LDAP Entry to be modified. The server SHALL NOT perform any alias dereferencing in determining the object to be modified.
changes - the sequence of LDAP ModifyRequest Operations to be performed on the LDAP Entry. The entire list of modifications MUST be performed in the order they are listed as a single atomic operation. While individual modifications may violate certain aspects of the directory schema (such as the ObjectClass Types and DIT Content Rule, the resulting LDAP Entry after the entire list of LDAP ModifyRequest Operations is performed MUST conform to the requirements of the directory model and controlling schema RFC 4512.
operation - specifies the LDAP ModifyRequest Operation of Modify Request being performed. Each LDAP ModifyRequest Operation acts on the following modification.
modification - Specifies the attribute within the LDAP Entry that the LDAP ModifyRequest Operation is to be performed on.

Modify Response #

Upon receipt of a Modify Request, the server attempts to perform the necessary modifications to the DIT and returns the result in a Modify Response. The server will return to the client a single Modify Response indicating either the successful completion of the DIT modification, or the reason that the modification failed.

Modify Request applies to LDAP Data Interchange Format (LDIF) operation also.

For LDIF the modify ChangeType directive is used along with the LDAP ModifyRequest Operations directive.
