 If not specified, port 8080 is used for http and https is disabled. Under Windows, you may change the http connector to use the standard port 80 instead, thus removing the need to type :8080 after domain name IP address in a browser. Under Linux/MacOS, you can not use ports below 1024.
-The above example is appropriate when using PIXILAB's Linux-based server, which provides an //nginx// reverse proxy managing the standard HTTP port 80 by forwarding to port 8080, mentioned above. Learn more about the nginx reverse proxy, including how it can also be used to support HTTPS connection, [[blocks:server:nginx|here]].

Learn more about the nginx reverse proxy, including how it can also be used to support HTTPS connection, [[blocks:server:nginx|here]]. The //useForwardedHeaders// option must be set to true when running Blocks behind a reverse proxy (and the reverse proxy must be configured to set allrelevant X-Forwarded-Xxx headers). If you're not using a reverse proxy (e.g., runnign Blocks on your Mac or Windows laptop), this setting can be omitted or set to false.
 See [[https://www.dropwizard.io/en/latest/manual/configuration.html#man-configuration-connectors|here]] for more details on advanced //applicationConnectors// settings. Those are advanced settings, that most users won't need. PIXILAB doesn't support servers where such advanced settings have been applied.

-Specifies advanced authentication and authorization options. In most cases, you don't need to specify these settings. Use only when specifically instructed to do so, e.g. for integration with single-sign-on systems such as [[blocks:sso:adfs|Active Directory]] or [[blocks:sso:okta|OKTA]].
+Specifies advanced authentication and authorization options. The settings shown above correspond to the defaults if no auth section is provided. In most cases, you don't need to specify these settings. If you specify the //internalForm// authorization method, a "Log Out" command will be added to Blocks' Page menu, allowing you to explicitly log out.   The OidcClient setting allows for integration with single-sign-on systems such as [[blocks:sso:adfs|Active Directory]] or [[blocks:sso:okta|OKTA]].
+:!: **IMPORTANT**: While the //internalForm// method provides log-out functionality, it also sends all authoriztion credentials, including your password, as clear text. The default //internalDigest// method, while not providing any log-out functionality, avoids sending your password as clear text. When using Blocks on publicly accessible networks, you're strongly advised to use and only allow [[blocks:server:nginx|encrypted connection#https_domain_name_and_certificate]] (HTTPS) for all editing operations.
