Das Asterisk Buch

Verlangt zur Fortsetzung eines Vorgangs die Eingabe eines Passworts vom Anrufer.

Authenticate(Passwort[,Optionen[,maxZiffern]])

Verlangt, dass der Anrufer ein gegebenes Passwort korrekt eingibt, um dann mit der Ausführung der nächsten Priorität im Dialplan fortzufahren. Authenticate() gibt dem Anrufer drei Versuche, das Passwort korrekt einzugeben. Andernfalls wird die Verbindung beendet.

Falls Passwort mit dem /-Zeichen beginnt, wird es als Datei interpretiert, die eine Liste gültiger Passwörter (genau eins pro Zeile) enthält. Passwörter können auch in der Asterisk-Datenbank (AstDB) gespeichert sein (siehe dazu die Option d weiter unten).

Folgende Optionen sind möglich (auch in Kombination):

	Wichtig
	Beachten Sie bei der Option d, dass – was wenig nachvollziehbar ist! – als Parameter /passwoerter/1234 verlangt wird, wobei passwoerter die Familie ist und 1234 das Passwort. Der unter diesem Schlüssel gespeicherte Wert ist irrelevant. Der gesunde Menschenverstand würde einen Datenbank-Eintrag wie /passwoerter/art => 1234 erwarten.

Mit Angabe von maxZiffern wird die Eingabe automatisch nach so vielen Ziffern beendet, ohne dass der User # drücken muss (Default: 0 für keine Begrenzung).

Liefert 0 zurück, falls der Benutzer nach maximal drei Versuchen ein gültiges Passwort eingegeben hat, sonst -1 (auch nach Auflegen).

[Synopsis]
Authenticate a user

[Description]
  Authenticate(password[|options[|maxdigits]]): This application asks the caller
to enter a given password in order to continue dialplan execution. If the password
begins with the '/' character, it is interpreted as a file which contains a list of
valid passwords, listed 1 password per line in the file.
  When using a database key, the value associated with the key can be anything.
Users have three attempts to authenticate before the channel is hung up. If the
passsword is invalid, the 'j' option is specified, and priority n+101 exists,
dialplan execution will continnue at this location.
  Options:
     a - Set the channels' account code to the password that is entered
     d - Interpret the given path as database key, not a literal file
     j - Support jumping to n+101 if authentication fails
     m - Interpret the given path as a file which contains a list of account
         codes and password hashes delimited with ':', listed one per line in
         the file. When one of the passwords is matched, the channel will have
         its account code set to the corresponding account code in the file.
     r - Remove the database key upon successful entry (valid with 'd' only)
     maxdigits  - maximum acceptable number of digits. Stops reading after
         maxdigits have been entered (without requiring the user to
         press the '#' key).
         Defaults to 0 - no limit - wait for the user press the '#' key.
