mod_http_oauth2: Allow 'login_hint' as a substitute for OIDC 'select_account' prompt
If the OIDC 'prompt' parameter does not contain the 'select_account'
then it wants us to skip account selection, which means we have to
figure which account to authenticate somehow. One way could be have
this stored in a cookie from a previous successful login. Another way
would be to have the account passed as a hint, which is what we add
here.

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 ------ -------
