Question
Answer and Explanation
Enabling LDAP authentication in Superset 4.0.2 involves configuring the application to communicate with your LDAP server. This process primarily involves modifying the superset_config.py file. Here’s a step-by-step guide:
1. Locate `superset_config.py`:
- Typically, this file is located in the same directory as your Superset installation's main Python package. You might find it within a directory like `superset/` or `apache-superset/`. Make sure to find the configuration file used by your installation.
2. Modify `superset_config.py` for LDAP:
- Open the `superset_config.py` file in a text editor and add or modify the following configurations. You will need to provide details specific to your LDAP setup.
- Example Configuration Snippet:
AUTH_TYPE = AUTH_LDAP
LDAP_SERVER = "ldap://your_ldap_server_address:389"
LDAP_BIND_USER = "cn=your_bind_user,dc=example,dc=com"
LDAP_BIND_PASSWORD = "your_bind_password"
LDAP_SEARCH_BASE = "dc=example,dc=com"
LDAP_SEARCH_FILTER = "(uid=%(username)s)"
LDAP_ACCOUNT_BASE = "ou=users,dc=example,dc=com"
LDAP_USE_TLS = False # Set to True if you're using LDAPS
LDAP_TLS_CACERTDIR = "/path/to/your/ca/certs/" # Required only if LDAP_USE_TLS = True
LDAP_TLS_CACERTFILE = "/path/to/your/ca.pem" # Required only if LDAP_USE_TLS = True
AUTH_USER_REGISTRATION = True # If you want to create the Superset user from LDAP
LDAP_ALLOW_SELF_SIGNED = True # Enable this option to enable self signed certificates (for development environment)
- Replace placeholders like `ldap://your_ldap_server_address:389`, `cn=your_bind_user,dc=example,dc=com`, and `dc=example,dc=com` with your actual LDAP server details. Make sure to use valid credentials for binding.
- Explanation of Key Parameters:
- `AUTH_TYPE`: Specifies the authentication method. Set this to `AUTH_LDAP` for LDAP authentication.
- `LDAP_SERVER`: The URL or IP address of your LDAP server.
-`LDAP_BIND_USER`: The user account used to bind to the LDAP server.
-`LDAP_BIND_PASSWORD`: The password for the bind user.
- `LDAP_SEARCH_BASE`: The base DN where user searches should start.
-`LDAP_SEARCH_FILTER`: The filter used to search for a user based on their username. The `%(username)s` is a placeholder for the entered username.
-`LDAP_ACCOUNT_BASE`: The base DN where user accounts are located, usually under an OU (Organizational Unit).
- `LDAP_USE_TLS`: Set to `True` if you're using LDAPS (LDAP over TLS).
-`LDAP_TLS_CACERTDIR`: Directory where your CA certificates are stored (if TLS is used).
- `LDAP_TLS_CACERTFILE`: Specific certificate file (if TLS is used).
-`AUTH_USER_REGISTRATION`: Set to `True` if users should be registered automatically in Superset upon their first login via LDAP.
- `LDAP_ALLOW_SELF_SIGNED`: Set to `True` if you use self signed certificates (not recommended in production).
3. Restart Superset:
- After saving your changes to `superset_config.py`, you need to restart the Superset server for the changes to take effect. Typically, this involves restarting the web server and the worker processes.
4. Test the LDAP Configuration:
- Try to log in using a valid LDAP user. If your configuration is correct, you should be able to log in to Superset using your LDAP credentials.
5. Troubleshooting:
- If authentication fails, enable debug logs in Superset to check for LDAP-related errors. Check the Superset logs to get more information.
- Make sure that your bind user has enough permissions on the LDAP server.
- Check if the `LDAP_SEARCH_FILTER` is correctly defined to find the user you intend to login.
By following these steps, you should be able to successfully enable LDAP authentication in Superset 4.0.2.
