Enabling OAUTH2 Authentication

To enable OAUTH2 authentication for pgAdmin, you must configure the OAUTH2 settings in the config_local.py or config_system.py file (see the config.py documentation) on the system where pgAdmin is installed in Server mode. You can copy these settings from config.py file and modify the values for the following parameters:

Parameter

Description

AUTHENTICATION_SOURCES

The default value for this parameter is internal. To enable OAUTH2 authentication, you must include oauth2 in the list of values for this parameter. you can modify the value as follows:

  • [‘oauth2’, ‘internal’]: pgAdmin will display an additional button for authenticating with oauth2

OAUTH2_NAME

The name of the Oauth2 provider, ex: Google, Github

OAUTH2_DISPLAY_NAME

Oauth2 display name in pgAdmin

OAUTH2_CLIENT_ID

Oauth2 Client ID

OAUTH2_CLIENT_SECRET

Oauth2 Client Secret

OAUTH2_TOKEN_URL

Oauth2 Access Token endpoint

OAUTH2_AUTHORIZATION_URL

Endpoint for user authorization

OAUTH2_SERVER_METADATA_URL

Server metadata url for your OAuth2 provider

OAUTH2_API_BASE_URL

Oauth2 base URL endpoint to make requests simple, ex: https://api.github.com/

OAUTH2_USERINFO_ENDPOINT

User Endpoint, ex: user (for github) and userinfo (for google)

OAUTH2_SCOPE

Oauth scope, ex: ‘openid email profile’. Note that an ‘email’ claim is required in the resulting profile.

OAUTH2_ICON

The Font-awesome icon to be placed on the oauth2 button, ex: fa-github

OAUTH2_BUTTON_COLOR

Oauth2 button color

OAUTH2_USERNAME_CLAIM
The claim which is used for the username. If the value is empty

the email is used as username, but if a value is provided, the claim has to exist. Ex: oid (for AzureAD)

OAUTH2_AUTO_CREATE_USER
Set the value to True if you want to automatically

create a pgAdmin user corresponding to a successfully authenticated Oauth2 user. Please note that password is not stored in the pgAdmin database.

OAUTH2_ADDITIONAL_CLAIMS
If a dictionary is provided, pgAdmin will check for a matching key and value on the userinfo endpoint

and in the Id Token. In case there is no match with the provided config, the user will receive an authorization error. Useful for checking AzureAD wids or groups, GitLab owner, maintainer and reporter claims.

OAUTH2_SSL_CERT_VERIFICATION
Set this variable to False to disable SSL certificate verification for OAuth2 provider.

This may need to set False, in case of self-signed certificates.

Redirect URL

The redirect url to configure Oauth2 server is <http/https>://<pgAdmin Server URL>/oauth2/authorize After successful application authorization, the authorization server will redirect the user back to the pgAdmin url specified here. Select https scheme if your pgAdmin server serves over https protocol otherwise select http.

Master Password

In the multi user mode, pgAdmin uses user’s login password to encrypt/decrypt the PostgreSQL server password. In the Oauth2 authentication, the pgAdmin does not store the user’s password, so we need an encryption key to store the PostgreSQL server password. To accomplish this, set the configuration parameter MASTER_PASSWORD to True, so upon setting the master password, it will be used as an encryption key while storing the password. If it is False, the server password can not be stored.

Login Page

After configuration, on restart, you can see the login page with the Oauth2 login button(s).
