PRTG Manual: LDAP Sensor

LDAP

This sensor officially supports Microsoft implementations of LDAP. Other third-party LDAP implementations might work but are not officially supported.

DNS name

This sensor requires a DNS name in the settings of the parent device if you use a Secure Sockets Layer (SSL)/Transport Layer Security (TLS) secured connection to the LDAP server.

Performance impact

This sensor has a medium performance impact.

IPv4

This sensor only supports IPv4.

Connection Security

Define if the sensor uses an SSL/TLS-secured connection to the LDAP server:

• Use LDAP without connection security (default)
• Use LDAP over SSL

If you select Use LDAP over SSL, you need to enter a DNS name in the settings of the parent device. The sensor does not work with an IP address.

Port Selection

Define if you want to use a default port or a custom port for the connection to the LDAP server:

• Use default port: Use the default port. This is port 389 for unsecure connections and port 636 for secure connections.
• Use custom port: Use a custom port. Specify the Port below.

Port

This setting is only visible if you select Use custom port above.

Enter a custom port for the connection to the LDAP server. Enter an integer.

Distinguished Name

Enter the distinguished name (DN) that you want to authenticate against the LDAP server. Usually, this is the information for the user that you want to authenticate with. For example, use the format cn=Manager,dc=my-domain,dc=com for a DN on an OpenLDAP server.

Password

Enter the password for the Distinguished Name.

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor.

You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.

Graph Type

Define how this sensor shows different channels:

• Show channels independently (default): Show a graph for each channel.
• Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
  You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

Stack Unit

This setting is only visible if you select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.

Downtime

In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status

Response Time

The response time

This channel is the primary channel by default.
