Bug: No PUBLIC_SERVER

[wmoore]

In order to allow access without login, via PUBLIC_USER and PUBLIC_PASSWORD settings, we also need to allow a PUBLIC_SERVER or use localhost by default.

Currently, the login_required get_connection() returns None quite early if there is no server defined:

if server_id is None:
# If no server id is passed, the db entry will not be used and
# instead we'll depend on the request.session and request.REQUEST
# values
    if connector is not None:
        server_id = connector.server_id
    else:
        try:
            server_id = request['server']
        except:
            logger.debug('No Server ID available.')
            return None

We are only logged in via the PUBLIC user if we actually login with a valid server, username and password.

Logic to fix these problems is now on the 8118_share_connection branch:

• ​https://github.com/aleksandra-tarkowska/openmicroscopy/commit/2ae66f8d1189eabef9273b6f52e33539916cce9f

[Chris Allan <callan@…>]

(In [2ae66f8d1189eabef9273b6f52e33539916cce9f/ome.git] on branch develop) Reorganised and expanded public user interaction. (See #8443, #8483)

There is now an additional 'omero.web.public.server_id' configuration
option which allows the system administrator to configure the desired
OMERO.server instance to use anonymous / public authentication with.
Furthermore this commit moves the connection retrieval logic into a two
stage process where the retrieval of an "authenticated" connection is
attempted first and if that fails or credentials are missing a "public"
connection attempt is then made.
