This module provides authproc-filters and authentication sources for interaction with LDAP directories.
Once you have installed SimpleSAMLphp, installing this module is very simple. Just execute the following command in the root of your SimpleSAMLphp installation:
composer.phar require simplesamlphp/simplesamlphp-module-ldap:dev-masterwhere dev-master instructs Composer to install the master branch from the
Git repository. See the releases
available if you want to use a stable version of the module.
Next thing you need to do is to enable the module: in config.php,
search for the module.enable key and set ldap to true:
    'module.enable' => [
         'ldap' => true,
         …
    ],
