mod_auth_cyrus: Add empty 'profile' table to SASL handler objects
This is for compatibility with Prosody's built-in util.sasl objects.
A SASL profile table usually includes methods supported by the backend, which
can be used by SASL mechanism handlers to perform operations (such as testing
the password). It also optionally contains a 'cb' field with channel binding
method handlers.
The Cyrus backend doesn't support channel binding, and doesn't have the same
concept of auth backend methods (it handles all that internally, and Prosody
has no insight or control over it).
Thus, we create an empty profile which informs Prosody that the SASL handler
does not support any of the auth or channel binding methods. Some features
will not work, but they didn't work anyway. This just makes it explicit.
This fixes a traceback in mod_sasl2_fast, which expected SASL handlers to
always contain a 'profile' field.

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