+attempting to sign in. If the user is found, the module attempts to bind to the
+server using the user's supplied credentials. If this succeeds, the user has
+been authenticated, and his account information is retrieved and passed to the
+Gogs login infrastructure.
+
+LDAP simple authentication does not utilize a Bind DN. Instead, it binds
+directly with the LDAP server using the user's supplied credentials. If the bind
+succeeds and no filter rules out the user, the user is authenticated.
+
+LDAP via BindDN is recommended for most users. By using a Bind DN, the server
+can perform authorization by restricting which entries the Bind DN account can
+read. Further, using a Bind DN with reduced permissions can reduce security risk
+in the face of application bugs.
