Authentication guide - Mattermost (self-hosted)

Note: The Mattermost setup portion of this document is just a quick guide. See the official documentation for more details.

This guide uses the generic OAuth2 module for compatibility with Mattermost version 5.0 and above.

  1. Sign-in with an administrator account to your Mattermost instance
  2. Make sure OAuth 2.0 Service Provider is enabled in the Main Menu (menu button next to your username in the top left corner) --> System Console --> Custom Integrations menu, which you can find at https://your.mattermost.domain/admin_console/integrations/custom

mattermost-enable-oauth2

  1. Navigate to the OAuth integration settings through Main Menu --> Integrations --> OAuth 2.0 Applications, at https://your.mattermost.domain/yourteam/integrations/oauth2-apps
  2. Click on the Add OAuth 2.0 Application button to add a new OAuth application

mattermost-oauth-app-add

  1. Fill out the form and click Save

mattermost-oauth-app-form

Note: The callback URL is <your-codimd-url>/auth/oauth2/callback

  1. After saving the application, you'll receive the Client ID and Client Secret

  1. Add the Client ID and Client Secret to your config.json file or pass them as environment variables
