Developed by Paessler, PRTG is network management software that monitors IT infrastructures composed of devices, applications, and systems.

But that’s not all. You can also use PRTG in distributed networks for the precise monitoring  of mail, web, database, and virtual servers – and in particular, LDAP servers.

Definition: What is LDAP?

LDAP (Lightweight Directory Access Protocol) is a simple network protocol for accessing directories. It is the only protocol that allows for communication between an LDAP client and a directory server. By monitoring your LDAP server, you’ll be able to make sure this communication is always running smoothly.

A “directory server” is an LDAP server or a computer that provides a directory service such as Microsoft Active Directory.

Meanwhile, an LDAP protocol refers to a data structure that is created in accordance with the specifications of LDAP.

LDAP in practice 

In practice, the communication between the client and server goes like this: An LDAP protocol is used to query (and store) information inside an LDAP directory. This information usually includes data on users, PCs, and the certificates of a computer. Two default ports are used here:

  • Port 389 for the unsecured transfer of data
  • Port 636 for the transfer of data secured by SSL/TLS

LDAP is an industry-standard authentication and authorization protocol. As a result, every corporate network is likely to have at least one LDAP server whose information should be monitored. Pretty much everything that deals with user data in some form or another supports the LDAP protocol:

  • Address data management software such as Outlook and Thunderbird
  • User management software such as Microsoft Active Directory Service and Apple Open Directory
  • Authentication solutions (e.g., Privileged Access Management)
  • User data management solutions for SMTP, POP, and IMAP servers

For network monitoring to be complete, it must also include the monitoring of all LDAP servers. This is where an LDAP monitoring tool like PRTG comes in.

Why LDAP server monitoring is a must

 

server 14 one forth

During LDAP monitoring, the focus isn’t so much on LDAP protocols but on LDAP servers. In particular, the monitoring tool monitors the following parameters of LDAP servers:

  1. Availability
  2. Performance
  3. Logon times
  4. Response times

These four system parameters are the key performance indicators. LDAP is typically used to authenticate user accounts and users (e.g., the employees of a company). When response times are too high and uptime too low, access to data becomes painstakingly slow – or even nonexistent. This not only causes headaches for users, but also reduces the productivity of your business.

 

Benefits for your business

With the right monitoring tool, your IT team can monitor the load and speed of your LDAP servers around the clock and immediately take action in the event of anomalies. In particular, LDAP monitoring lets you:

 

Server threshold monitoringDramatically increase the availability of servers, applications, and services

Server threshold monitoringQuickly detect critical performance issues and resolve them immediately – thereby restoring availability

Server threshold monitoringPrevent network crashes – or reduce them to an absolute minimum

Quick start: LDAP monitoring with PRTG

 

PRTG is an outstanding LDAP monitoring tool. It comes with a predefined LDAP Sensor for monitoring LDAP servers. This sensor is certified as compatible with Microsoft products based on LDAP. It also works with LDAP integrations from other providers, albeit in a non-certified capacity.

Setting up the LDAP Sensor is quick and easy.

When adding the sensor for the first time, a dialog box appears which lets you select or define your LDAP monitoring settings.

Step 1

Create a name for the sensor and (if necessary) tags to improve the classification of the data.

Step 2

Choose whether you wish to establish a secure (SSL) or unsecure connection to the LDAP server.

Step 3

Choose between the default ports 389 and 636 or another port defined by you.

Step 4

Specify the DN (distinguished name).

Step 5

Enter the password for the DN (to authenticate the LDAP server).

Step 6

Specify the settings for the scanning intervals, monitoring schedules, and more.

 

Note: If you opt for a secure (SSL/TLS) connection, then the sensor will require a DNS name in the settings of the parent device for the configuration. The sensor only supports the IPv4 protocol and has a moderate impact on performance.

 So how does an IT team monitor LDAP servers with PRTG?

 i What is a sensor?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

Here’s how it works: PRTG comes equipped with an LDAP Sensor that connects to the LDAP server (or directory) and measures the response time. Technically speaking, this connection is called a “bind” operation, i.e., a login to the LDAP server using the “bind” command.

If the server stops responding (or the response time exceeds a predefined limit), PRTG sends an alert at once. IT administrators receive the alert on their desktop PC or as a push notification on their smartphone. As a result, they can quickly step in and fix the problem.
