8.3. Integration with LDAP
CUBA applications can be integrated with LDAP to provide the following benefits:
Storing user passwords centrally in the LDAP database.
For Windows domain users, ability to log in using Single Sign-On without having to specify the username and password.
If the LDAP integration is enabled, a user still needs an account in the application. All the user permissions and properties (except password) are stored in the application database, LDAP is used only for authentication. When the user logs in to the application, the first authentication attempt is made via LDAP. If it fails, the application tries to authenticate the user by the password hash stored in the database. As a result, a user can log in to the system with this password even if he is not registered in LDAP or has a different LDAP password. However, it is recommended to leave the application password empty, so that the user could log in using the password from LDAP only (the password field in the user editor screen is not required if the cuba.web.externalAuthentication property is set to
A CUBA-based application interacts with LDAP via the
CubaAuthProvider interface. The platform includes a single implementation of this interface,
LdapAuthProvider, which supports LDAP authentication.
You can use the Jespa library with the corresponding
CubaAuthProvider described in the Active Directory Integration Using Jespa section in order to enable advanced integration with Active Directory, including Single Sign-On for Windows domain users.
You can also create your own implementation of the
CubaAuthProvider interface and use it by setting the following application properties:
cuba.web.externalAuthentication = true cuba.web.externalAuthenticationProviderClass = com.company.sample.web.MyAuthProvider
