• Force authentication

    I have forgotten the reason for setting "force authentication" in a
    newsreader.

    Is this because a server wants the newsreader to provide the user's
    credentials but doesn't initiate the request in the greeting dialogue? Is it because the server is set not to ask as it expects the newsreader to offer credentials without prompting? Or is it because the newsreader won't
    provide credentials when prompted to unless this feature is set?

    I've got a vague recollection of using long defunct servers for which I provided credentials but didn't force authentication. There must be a historical reason for the additional step.

    Some servers (e.g. ES) provides a small amount of groups for read (or
    even write) access without authentication. The newsreader doesn't try authentication unless it is being prompted by the server to do so - or
    forced by the setting.

    For the group list, the servers allows unauthenticated retrieval for
    some hierarchies, but not all. The newsreader does not know that the
    server provides even more after authentication.

    The "force authentication" options is required with newsreaders that
    rely on the server greeter ("posting ok") and will only use authinfo
    user/pass when this info is missing from the greeter.

    Since Eternal-September accepts posts for the eternal-september.*
    hierarchy without authentication and the greeter is sent /before/ the user enters a group, it will always send "posting ok" and complain when the
    users tries to enter a group that is only accessible to authenticated
    users(*).
    To set these newsreaders to use authinfo user/pass despite the "posting ok" greeter, "Force authentication" is needed (the actual wording may vary depending on the newsreader).

    My current active file with trn settings has two defunct servers
    commented out in which authentication was required but I didn't force authentication, news.albasani.net and a private server. Now albasani
    requred authentication to post. Without receiving "posting ok", the
    newsreader offered user/pass during greeting dialogue if I'm understanding
    you.

    I found any number of defunct servers commented out that required authentication for which I forced authentication. At least in my
    experience of using various servers in more recent years, it's been more
    common than not.

    This is not my original active file.

    Albasani /always/ required a username and password, hence it never sent
    the "posting ok" greeter and newsreader always sent the credentials. The
    user name for read-only access was "readonly", the password was
    "readonly", too.
