Overview#

The LDAP cancel extended operation is an extended operation that provides a function similar to the core Abandon Request in that it can be used to request that the server stop processing on an operation in progress.

The primary advantages of the cancel extended operation over the abandon operation are that both the cancel request and the operation being canceled are guaranteed to get a response, whereas there is no response for the Abandon Request and there may not be a response for the operation being abandoned.

The cancel extended operation is defined in RFC 3909. The value of the cancel request extended operation is encoded as follows:

      
cancelRequestValue ::= SEQUENCE {
     cancelID        MessageID
     -- MessageID is as defined in [RFC2251]
}
