mod_rest: Do not allow replies to <iq type=result> from webhooks
Replying to a result stanza could cause loops, just as replying to an
error.
No stanza.name check here but it should be fine since no other kinds of
stanzas have type=result, and the boolean logic would most definitely be
wrong on the first attempt.

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 `{ "admin" }` 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 ============= ----- ------------- 0.9 Works 0.8 Should work ----- -------------
