Implement remote user login source and promotion to regular user A remote user (UserTypeRemoteUser) is a placeholder that can be promoted to a regular user (UserTypeIndividual). It represents users that exist somewhere else. Although the UserTypeRemoteUser already exists in Forgejo, it is neither used or documented. A new login type / source (Remote) is introduced and set to be the login type of remote users. Type UserTypeRemoteUser LogingType Remote The association between a remote user and its counterpart in another environment (for instance another forge) is via the OAuth2 login source: LoginName set to the unique identifier relative to the login source LoginSource set to the identifier of the remote source For instance when migrating from GitLab.com, a user can be created as if it was authenticated using GitLab.com as an OAuth2 authentication source. When a user authenticates to Forejo from the same authentication source and the identifier match, the remote user is promoted to a regular user. For instance if 43 is the ID of the GitLab.com OAuth2 login source, 88 is the ID of the Remote loging source, and 48323 is the identifier of the foo user: Type UserTypeRemoteUser LogingType Remote LoginName 48323 LoginSource 88 Email (empty) Name foo Will be promoted to the following when the user foo authenticates to the Forgejo instance using GitLab.com as an OAuth2 provider. All users with a LoginType of Remote and a LoginName of 48323 are examined. If the LoginSource has a provider name that matches the provider name of GitLab.com (usually just "gitlab"), it is a match and can be promoted. The email is obtained via the OAuth2 provider and the user set to: Type UserTypeIndividual LogingType OAuth2 LoginName 48323 LoginSource 43 Email foo@example.com Name foo Note: the Remote login source is an indirection to the actual login source, i.e. the provider string my be set to a login source that does not exist yet.
