Public Instance Methods

Adds an authenticator for Net::IMAP#authenticate to use. mechanism is the SASL mechanism implemented by authenticator (for instance, "PLAIN").

The authenticator must respond to #new (or call), receiving the authenticator configuration and return a configured authentication session. The authenticator session must respond to #process, receiving the server’s challenge and returning the client’s response.

See PlainAuthenticator, XOauth2Authenticator, and DigestMD5Authenticator for examples.

# File net-imap-0.3.4/lib/net/imap/authenticators.rb, line 17
def add_authenticator(auth_type, authenticator)
  authenticators[auth_type] = authenticator
authenticator(mechanism, ...) → authenticator click to toggle source
authenticator(mech, *creds, **props) {|prop, auth| val } → authenticator
authenticator(mechanism, authnid, creds, authzid=nil) → authenticator
authenticator(mechanism, **properties) → authenticator
authenticator(mechanism) {|propname, authctx| value } → authenticator

Builds a new authentication session context for mechanism.


This method is intended for internal use by connection protocol code only. Protocol client users should see refer to their client’s documentation, e.g. Net::IMAP#authenticate for Net::IMAP.

The call signatures documented for this method are recommendations for authenticator implementors. All arguments (other than mechanism) are forwarded to the registered authenticator’s #new (or #call) method, and each authenticator must document its own arguments.

The returned object represents a single authentication exchange and must not be reused for multiple authentication attempts.
