 ### Configuration
 
-To configure your application, you need to create a file `superset_config.py` and add it to your
-`PYTHONPATH`. If your application was installed using docker compose an alternative configuration is required. See [https://github.com/apache/superset/tree/master/docker#readme](https://github.com/apache/superset/tree/master/docker#readme) for details.
+To configure your application, you need to create a file `superset_config.py`.  Add this file to your
+
+`PYTHONPATH` or create an environment variable `SUPERSET_CONFIG_PATH` specifying the full path of the `superset_config.py`.
+
+For example, if deploying on Superset directly on a Linux-based system where your `superset_config.py` is under `/app` directory, you can run:
+```bash
+export SUPERSET_CONFIG_PATH=/app/superset_config.py
+```
+
+If you are using your own custom Dockerfile with official Superset image as base image, then you can add your overrides as shown below:
+```bash
+COPY --chown=superset superset_config.py /app/
+ENV SUPERSET_CONFIG_PATH /app/superset_config.py
+```
+
+Docker compose deployments handle application configuration differently.  See [https://github.com/apache/superset/tree/master/docker#readme](https://github.com/apache/superset/tree/master/docker#readme) for details.
 
 The following is an example of just a few of the parameters you can set in your `superset_config.py` file:

+### Mapping LDAP or OAUTH groups to Superset roles
+
+AUTH_ROLES_MAPPING in Flask-AppBuilder is a dictionary that maps from LDAP/OAUTH group names to FAB roles.
+It is used to assign roles to users who authenticate using LDAP or OAuth.
+
+#### Mapping OAUTH groups to Superset roles
+
+The following AUTH_ROLES_MAPPING dictionary would map the OAUTH group "superset_users" to the Superset roles "Gamma" as well as "Alpha", and the OAUTH group "superset_admins" to the Superset role "Admin".
+
+AUTH_ROLES_MAPPING = {
+"superset_users": ["Gamma","Alpha"],
+"superset_admins": ["Admin"],

+#### Mapping LDAP groups to Superset roles
+
+The following AUTH_ROLES_MAPPING dictionary would map the LDAP DN "cn=superset_users,ou=groups,dc=example,dc=com" to the Superset roles "Gamma" as well as "Alpha", and the LDAP DN "cn=superset_admins,ou=groups,dc=example,dc=com" to the Superset role "Admin".

+"cn=superset_users,ou=groups,dc=example,dc=com": ["Gamma","Alpha"],

+
+Note: This requires AUTH_LDAP_SEARCH to be set. For more details, Please refer (FAB Security documentation)[https://flask-appbuilder.readthedocs.io/en/latest/security.html].
+
+#### Syncing roles at login
+
+You can also use the AUTH_ROLES_SYNC_AT_LOGIN configuration variable to control how often Flask-AppBuilder syncs the user's roles with the LDAP/OAUTH groups. If AUTH_ROLES_SYNC_AT_LOGIN is set to True, Flask-AppBuilder will sync the user's roles each time they log in. If AUTH_ROLES_SYNC_AT_LOGIN is set to False, Flask-AppBuilder will only sync the user's roles when they first register.
