Further development orders are possible. This bundle adds LDAP functionality for Contao backend and frontend users/groups. Requirements ------------ [](#requirements) For everything to work you need to install and activate the PHP extension "php-ldap". Without it you can not install and use this Bundle Beside that you need at least the Contao Version 4.9. Installation ------------ [](#installation) ### Step 1: Install the bundle [](#step-1-install-the-bundle) You can install the bundle using composer or the contao manager. For composer use the following command: ``` $ composer require con4gis/ldap ``` In the contao manager, you can find the bundle under "con4gis/ldap". ### Step 2: Configure the bundle [](#step-2-configure-the-bundle) After the installationy you need to add the files "security.yml" and "services.yml" to your config folder in the root folder of your installation. If the file "config.yml" doesn't exist create it too. Then you need to add the following configurations to these files: **services.yml:** ``` services: Symfony\Component\Ldap\Ldap: arguments: ['@Symfony\Component\Ldap\Adapter\ExtLdap\Adapter'] Symfony\Component\Ldap\Adapter\ExtLdap\Adapter: arguments: - host: ad.yourldapserver.com port: 389 encryption: tls options: protocol_version: 3 referrals: false ``` In the services.yml you need to change the host to where your LDAP server is available. If you don't use the standard port change it here to (SSL is normally port 636). For the encryption, you can choose between "none" (not recommended), "ssl" and "tls". **security.yml:** ``` security: providers: con4gis_ldap: ldap: service: Symfony\Component\Ldap\Ldap base_dn: 'dc=ad,dc=yourldapserver,dc=com' search_dn: 'cn=Administrator,cn=Users,dc=ad,dc=yourldapserver,dc=com' search_password: '*Password*' default_roles: ROLE_USER uid_key: uid filter: '(objectClass=user)' chain_provider_backend: chain: provider: [contao.security.backend_user_provider, con4gis_ldap] chain_provider_frontend: chain: provider: [contao.security.frontend_user_provider, con4gis_ldap] firewalls: contao_backend: provider: chain_provider_backend form_login_ldap: service: Symfony\Component\Ldap\Ldap dn_string: 'uid={username},ou=Users,dc=ad,dc=yourldapserver,dc=com' contao_frontend: provider: chain_provider_frontend form_login_ldap: service: Symfony\Component\Ldap\Ldap dn_string: 'uid={username},ou=Users,dc=ad,dc=yourldapserver,dc=com' ``` In this configuration file, you need to change a few things. These include the "base\_dn", "search\_dn", "search\_password", "uid\_key", "filter" and both "dn\_string" at ""contao\_backend" and "contao\_frontend". The uid\_key needs to contain the attribute which contains the username. Normally it's "uid" or "sAMAccountName" (for Windows AD). You can filter which user can log in with the "filter". This is completely optional. If you don't want this delete the line. The dn\_string can contain two placeholders: "{username}" and "{uid\_key}". These placeholders will be replaced with the username of the login request respectively the uid\_key you set up earlier. **config.yml:** ``` imports: - { resource: security.yml } - { resource: services.yml } ``` Here you need to import the newly created files. After these changes, you need to clear the Symfony cache for everything to work. ### Step 3: Configure the groups [](#step-3-configure-the-groups) Now you can login to the Backend and configure everything else from there. You can import user and member groups from your LDAP server and select an admin group. ### Health Score 34 — LowBetter than 77% of packages Maintenance24 Infrequent updates — may be unmaintained Popularity16 Limited adoption so far Community19 Small or concentrated contributor base Maturity68 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.

It fully supports OpenLDAP and Active Directory and is capable of connecting securely to the authentication server using either TLS or SSL (ldaps://). In case of use in an intranet environment, this extension is a perfect match since it natively brings Single Sign-On (SSO) capability to TYPO3 without any complex configuration. 33377.4k](/packages/causal-ig-ldap-sso-auth)[edvlerblog/yii2-adldap-module yii2 Active Directory implementation (wrapper for Adldap2) 51227.3k](/packages/edvlerblog-yii2-adldap-module)[ldaptools/ldaptools-bundle Provides easy LDAP integration for Symfony via LdapTools. 49159.5k](/packages/ldaptools-ldaptools-bundle)[chrmorandi/yii2-ldap Ldap 1453.1k](/packages/chrmorandi-yii2-ldap) PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
