How To Fix “authconfig: command not found” Error in Ubuntu

Ubuntu 8

If you’ve been working with Ubuntu, you might have encountered the error “authconfig: command not found”. This error arises because the authconfig command, which is commonly used for configuring system authentication resources, is not available in Ubuntu 14.04 and later versions. But don’t worry, there are alternatives that you can use to achieve the same purpose. In this article, we’ll guide you through the process of fixing this error using the System Security Services Daemon (SSSD) and the LDAP authentication configuration package.

Quick Answer

To fix the "authconfig: command not found" error in Ubuntu, you can use alternatives such as the System Security Services Daemon (SSSD) or the LDAP authentication configuration package. These tools provide similar functionality to the authconfig command and can be used to configure system authentication resources.

Understanding the Error

The authconfig command is a utility that configures system authentication resources. It’s typically used in Red Hat-based systems and is not packaged with Ubuntu. When you try to use this command in Ubuntu, you’ll encounter the “authconfig: command not found” error.

The Alternative: System Security Services Daemon (SSSD)

SSSD is a software package that provides access to remote directories and authentication mechanisms. It offers an alternative to the authconfig command and can be used with OpenLDAP for authentication.

Installing SSSD

To install SSSD, open your terminal and type the following command:

sudo apt-get install sssd

This command uses the apt-get package handling utility to install SSSD. The sudo command is used to execute the command with root privileges.

Configuring SSSD

After installing SSSD, you’ll need to configure it. The configuration file is located at /etc/sssd/sssd.conf. You can use a text editor like nano to open and edit this file.

sudo nano /etc/sssd/sssd.conf

In this file, you’ll need to specify your domain and the services that SSSD should manage. For more details on how to configure SSSD, you can refer to the SSSD documentation.

LDAP Authentication Configuration Package

Another alternative is to use the LDAP authentication configuration package. This package can be installed using the apt command.

Installing the LDAP Authentication Configuration Package

To install the LDAP authentication configuration package, use the following command:

sudo apt install ldap-auth-config

This command will prompt you for the LDAP server details, such as the server name or IP, port number, and CN, OU, and DC information.

Conclusion

While the “authconfig: command not found” error can be frustrating, it’s important to remember that there are viable alternatives available. By using SSSD or the LDAP authentication configuration package, you can effectively manage authentication on your Ubuntu system. Always remember to refer to the official documentation for these tools for the most accurate and detailed information.
