- # constructed as "firstinitial.secondinitial.familyname" when applied to
- # a name without a second initial.) However, a local part starting
- # with a dot or containing /../ can cause trouble if it is used as part of a
- # file name (e.g. for a mailing list). This is also true for local parts that
- # contain slashes. A pipe symbol can also be troublesome if the local part is
- # incorporated unthinkingly into a shell command line.

- # The examples below are for server side authentication, when the
- # local exim is SMTP server and clients authenticate to the local exim.
- # They allow two styles of plain-text authentication against an
- # CONFDIR/passwd file whose syntax is described in exim4_passwd(5).
- # Hosts that are allowed to use AUTH are defined by the
- # auth_advertise_hosts option in the main configuration. The default is
- # "*", which allows authentication to all hosts over all kinds of
- # connections if there is at least one authenticator defined here.
- # Authenticators which rely on unencrypted clear text passwords don't
- # advertise on unencrypted connections by default. Thus, it might be
- # wise to set up TLS to allow encrypted connections. If TLS cannot be
- # used for some reason, you can set AUTH_SERVER_ALLOW_NOTLS_PASSWORDS to
- # advertise unencrypted clear text password based authenticators on all
- # connections. As this is severely reducing security, using TLS is
- # preferred over allowing clear text password based authenticators on
- # unencrypted connections.
- # PLAIN authentication has no server prompts. The client sends its
- # credentials in one lump, containing an authorization ID (which we do not
- # use), an authentication ID, and a password. The latter two appear as
- # $auth2 and $auth3 in the configuration and should be checked against a
- # valid username and password. In a real configuration you would typically
- # use $auth2 as a lookup key, and compare $auth3 against the result of the
- # lookup, perhaps using the crypteq{}{} condition.
- # plain_server:
- # driver = plaintext
- # public_name = PLAIN
- # server_condition = "${if crypteq{$auth3}{${extract{1}{:}{${lookup{$auth2}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{1}{0}}"

- # server_prompts = :
- # .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
- # server_advertise_condition = ${if eq{$tls_cipher}{}{}{*}}

- # LOGIN authentication has traditional prompts and responses. There is no
