mod_http_oauth2: Do minimal validation of private-use URI schemes
Per draft-ietf-oauth-v2-1-08#section-2.3.1
> At a minimum, any private-use URI scheme that doesn't contain a period
> character (.) SHOULD be rejected.
Since this would rule out the OOB URI, which is useful for CLI tools and
such without a built-in http server, it is explicitly allowed.

Introduction ============ On a server with public registration it is usually desirable to prevent registration of certain "reserved" accounts, such as "admin". This plugin allows you to reserve individual usernames, or those matching certain patterns. It also allows you to ensure that usernames conform to a certain pattern. Configuration ============= Enable the module as any other: modules_enabled = { "block_registrations"; } You can then set some options to configure your desired policy: Option Default Description ------------------------------ ------------------- ----------------------------------------------------------------------------------------------------------------------------------------------- block_registrations_users *See source code* A list of reserved usernames block_registrations_matching `{ }` A list of [Lua patterns](http://www.lua.org/manual/5.1/manual.html#5.4.1) matching reserved usernames (slower than block_registrations_users) block_registrations_require `nil` A pattern that registered user accounts MUST match to be allowed Some examples: block_registrations_users = { "admin", "root", "xmpp" } block_registrations_matching = { "master$" -- matches anything ending with master: postmaster, hostmaster, webmaster, etc. } block_registrations_require = "^[a-zA-Z0-9_.-]+$" -- Allow only simple ASCII characters in usernames Compatibility ============= ------ ------- 0.12 Works 0.11 Work ------ -------
