LDAP authentication into your Symfony application

Integrating LDAP authentication into your Symfony application can be a great way to provide secure access to external users from an LDAP server. By connecting to an LDAP server, you can authenticate users using their existing LDAP credentials, allowing them to seamlessly log in to your application.

To get started, you’ll need to configure your application to connect to the LDAP server. This includes specifying the server address, port, and bind credentials in your Symfony configuration files. You can do this by adding the necessary configuration options to your security.yaml file, which is located in the config/packages directory of your Symfony application.

In this configuration, the base_dn option specifies the base distinguished name of the LDAP directory, while the search_dn and search_password options specify the credentials to use when searching for a user by username and uid_key options specify the attributes to use for the user’s username.

Now, add a service to the services.yaml file

If you are using a testing tool such as Postman, you can open it and hit the endpoint to get the token in the response.

Now, copy the token and paste it into the JWT debugger tool, which decodes and verify the jwt token.You should see data something like this after pasting the token into the JWT debugger.

The LDAP data that I am fetching can be found in the following location.
