- The DN of the user as whom the connection should be

- The change listener to be registered with the server.

- The types of changes for which the listener should be
registered. It may be null

indicate that the listener should be registered for
all types of changes.baseDNs
- The set of base DNs for which the listener should be
registered. It may be null

indicate that the listener should be registered for
changes processed anywhere in the server.filter
- A filter which may be used to restrict the set of
changes for which the listener is notified. If a
filter is provided, then only changes in which the
target entry matches the given filter (either before
or after the change was processed) will be notified.
It may be null
to indicate that the contents
of the entry should not be considered.

of the base DNs cannot be parsed as a valid DN).void deregisterChangeListener(RegisteredChangeListener listener)

.RegisteredMonitorProvider registerMonitorProvider(MonitorProvider provider, GenericConfig config)
IllegalStateException
will be
thrown.
The generated monitor entry will have a DN in the following format:
cn={monitor-instance-name} [from {extension-type}:{extension-name}],
cn=monitor
and it will contain three auto-generated attributes:
ds-extension-monitor-name
, ds-extension-type
, and
ds-extension-name
. Note: the {extension-type} and
{extension-name} are from the extension which owns this ServerContext
instance, not from the given MonitorProvider object.
The specified monitor provider does not need any server-side configuration,
and the configuration-related methods
(initalizeMonitorProvider()
,
finalizeMonitorProvider()
,
defineConfigArguments()
,
isConfigurationAcceptable()
,
applyConfiguration()
) do not need to be implemented because
they will not be called.
When an extension is disabled, all of its registered monitor
providers will automatically deregister themselves from the server.
You can also manually deregister them using
deregisterMonitorProvider(RegisteredMonitorProvider)
or
deregisterAllMonitorProviders()
.
provider
- The monitor provider instance to be registered. It
must not be null
.config
- The configuration object from the extension that is
registering the given monitor provider. This is required so
that the monitor entry can be given a unique DN which
includes the name of the extension that registered it.
void deregisterMonitorProvider(RegisteredMonitorProvider provider)
provider
- The monitor provider instance to be registered. It
must not be null
.void deregisterAllMonitorProviders()
ServerContext
. This can be useful during
cleanup or if you want to clear out all the existing monitor data from a
given extension and register new monitor providers.
This will be called automatically when your extension is unloaded or disabled.

.void sendAlert(java.lang.String alertTypeName, AlertSeverity severity, java.lang.String alertTypeOID, java.lang.String message) throws LDAPException
alertTypeName
- The name to use to identify the alert type. Each
kind of alert must have a distinct name and all
alerts with this alert type must always be used with
the same severity and OID values. Alert type names
must start with a lowercase ASCII letter and must
contain only lowercase ASCII letters, numeric
digits, and dashes.severity
- The severity to use for the alert notification.
It must not be null
.alertTypeOID
- The numeric OID for the alert type. It must not be

a unique OID.message

- If the provided information cannot be used to
generate a valid alert (e.g., if the alert type
