This leverages the existing `sync_external_users` cron job to synchronize the `IsActive` flag on users who use an OAuth2 provider set to synchronize. This synchronization is done by checking for expired access tokens, and using the stored refresh token to request a new access token. If the response back from the OAuth2 provider is the `invalid_grant` error code, the user is marked as inactive. However, the user is able to reactivate their account by logging in the web browser through their OAuth2 flow. Also changed to support this is that a linked `ExternalLoginUser` is always created upon a login or signup via OAuth2. ### Notes on updating permissions Ideally, we would also refresh permissions from the configured OAuth provider (e.g., admin, restricted and group mappings) to match the implementation of LDAP. However, the OAuth library used for this `goth`, doesn't seem to support issuing a session via refresh tokens. The interface provides a [`RefreshToken` method](https://github.com/markbates/goth/blob/master/provider.go#L20), but the returned `oauth.Token` doesn't implement the `goth.Session` we would need to call `FetchUser`. Due to specific implementations, we would need to build a compatibility function for every provider, since they cast to concrete types (e.g. [Azure](https://github.com/markbates/goth/blob/master/providers/azureadv2/azureadv2.go#L132)) --------- Co-authored-by: Kyle D <kdumontnu@gmail.com>
