+.B cancel {ABANDON|ignore|exop[-discover]}
+Defines how to handle operation cancellation.
+By default,
+.B abandon
+is invoked, so the operation is abandoned immediately.
+If set to
+.BR ignore ,
+no action is taken and any further response is ignored; this may result
+in further response messages to be queued for that connection, so it is
+recommended that long lasting connections are timed out either by
+.I idle-timeout
+or
+.IR conn-ttl ,
+so that resources eventually get released.
+If set to
+.BR exop ,
+a
+.I cancel
+operation (RFC 3909) is issued, resulting in the cancellation
+of the current operation; the
+.I cancel
+operation waits for remote server response, so its use
+may not be recommended.
+If set to
+.BR exop-discover ,
+support of the
+.I cancel
+extended operation is detected by reading the remote server's root DSE.

+.B quarantine <interval>,<num>[;<interval>,<num>[...]]
+Turns on quarantine of URIs that returned
+.IR LDAP_UNAVAILABLE ,
+so that an attempt to reconnect only occurs at given intervals instead
+of any time a client requests an operation.
+The pattern is: retry only after at least
+.I interval
+seconds elapsed since last attempt, for exactly
+.I num
+times; then use the next pattern.
+If
+.I num
+for the last pattern is "\fB+\fP", it retries forever; otherwise,
+no more retries occur.
+The process can be restarted by resetting the \fIolcDbQuarantine\fP
+attribute of the database entry in the configuration backend.
