How does the authentication differ on author and publish
- LDAP and SMAL are only for author ? what if I have to use SMAL or LDAP on publish.
- How does authentication works on publish , if I have to make a part of content (content/en/members) secure and available to authorized members how can I do that ?
As @Opkar mentioned, you can have any authentication model for the form (login) either in Author or Publish instance. You need to just call that authentication service when you submit the login form in the publish instance.
