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, 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)

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 OAuth flow.

Also changed to support this is that a linked `ExternalLoginUser` is
always created upon a login or signup via OAuth2.
