appliance has one built-in monitor that can be used to monitor LDAP services:
LDAP monitor. It periodically checks the LDAP
service to which it is bound by authenticating and sending a search query to
it. If the search is successful, the service is marked UP. If the LDAP server
does not locate the entry, a failure message is sent to the LDAP monitor, and
the service is marked DOWN.
You configure the
LDAP monitor to define the search that it should perform when sending a query.
You can use the Base DN parameter to specify a location in the directory
hierarchy where the LDAP server should start the test query. You can use the
Attribute parameter to specify an attribute of the target entity.
Note: Monitor probes originate from the NetScaler IP (NSIP) address.
