+module: bigip_monitor_ldap
+short_description: Manages BIG-IP LDAP monitors
+description:
+  - Manages BIG-IP LDAP monitors.
+version_added: 2.8
+options:
+  name:
+    description:
+      - Monitor name.
+    required: True
+  description:
+    description:
+      - Specifies descriptive text that identifies the monitor.
+  parent:
+    description:
+      - The parent template of this monitor template. Once this value has
+        been set, it cannot be changed.
+      - By default, this value is the C(ldap) parent on the C(Common) partition.
+    default: "/Common/ldap"
+  ip:
+    description:
+      - IP address part of the IP/port definition. If this parameter is not
+        provided when creating a new monitor, then the default value will be
+        '*'.
+  port:
+    description:
+      - Port address part of the IP/port definition. If this parameter is not
+        provided when creating a new monitor, then the default value will be
+        '*'.
+      - Note that if specifying an IP address, a value between 1 and 65535
+        must be specified.
+  interval:
+    description:
+      - Specifies, in seconds, the frequency at which the system issues the
+        monitor check when either the resource is down or the status of the
+        resource is unknown.
+  timeout:
+    description:
+      - Specifies the number of seconds the target has in which to respond to
+        the monitor request.
+      - If the target responds within the set time period, it is considered 'up'.
+        If the target does not respond within the set time period, it is considered
+        'down'. When this value is set to 0 (zero), the system uses the interval
+        from the parent monitor.
+      - Note that C(timeout) and C(time_until_up) combine to control when a
+        resource is set to up.
+  time_until_up:
+    description:
+      - Specifies the number of seconds to wait after a resource first responds
+        correctly to the monitor before setting the resource to 'up'.
+      - During the interval, all responses from the resource must be correct.
+      - When the interval expires, the resource is marked 'up'.
+      - A value of 0, means that the resource is marked up immediately upon
+        receipt of the first correct response.
+  up_interval:
+    description:
+      - Specifies the interval for the system to use to perform the health check
+        when a resource is up.
+      - When C(0), specifies that the system uses the interval specified in
+        C(interval) to check the health of the resource.
+      - When any other number, enables specification of a different interval to
+        use when checking the health of a resource that is up.
+  manual_resume:
+    description:
+      - Specifies whether the system automatically changes the status of a resource
+        to B(enabled) at the next successful monitor check.
+      - If you set this option to C(yes), you must manually re-enable the resource
+        before the system can use it for load balancing connections.
+      - When C(yes), specifies that you must manually re-enable the resource after an
+        unsuccessful monitor check.
+      - When C(no), specifies that the system automatically changes the status of a
+        resource to B(enabled) at the next successful monitor check.
+    type: bool
+  target_username:
+    description:
+      - Specifies the user name, if the monitored target requires authentication.
+  target_password:
+    description:
+      - Specifies the password, if the monitored target requires authentication.
+  base:
+    description:
+      - Specifies the location in the LDAP tree from which the monitor starts the
+        health check.
+  filter:
+    description:
+      - Specifies an LDAP key for which the monitor searches.
+  security:
+    description:
+      - Specifies the secure protocol type for communications with the target.
+    choices:
+      - none
+      - ssl
+      - tls
+  mandatory_attributes:
+    description:
+      - Specifies whether the target must include attributes in its response to be
+        considered up.
+    type: bool
+  chase_referrals:
+    description:
+      - Specifies whether, upon receipt of an LDAP referral entry, the target
+        follows (or chases) that referral.
+    type: bool
+  debug:
+    description:
+      - Specifies whether the monitor sends error messages and additional information
+        to a log file created and labeled specifically for this monitor.
+    type: bool
+  update_password:
+    description:
+      - C(always) will update passwords if the C(target_password) is specified.
+      - C(on_create) will only set the password for newly created monitors.
+    default: always
+    choices:
+      - always
+      - on_create
+  partition:
+    description:
+      - Device partition to manage resources on.
+    default: Common
+  state:
+    description:
+      - When C(present), ensures that the monitor exists.
+      - When C(absent), ensures the monitor is removed.
+    default: present
+    choices:
+      - present
+      - absent
