authpam.py - A PAM Authentication Module
This authentication module is built on top of gopam.py which is included with
Gate One.
It was originally written by Alan Schmitz.
The only non-obvious aspect of this module is that the pam_realm setting is only
used when the user is asked to authenticate and when the user's information is
stored in the 'users' directory. It isn't actually used in any part of the
authentication (PAM doesn't take a "realm" setting).
-
class authpam.PAMAuthMixin(application, request, **kwargs)[source]
This is used by PAMAuthHandler in auth.py to authenticate users via PAM.
-
initialize()[source]
Print out helpful error messages if the requisite settings aren't
configured.
-
get_authenticated_user(callback)[source]
Processes the client's Authorization header and call self.auth_basic()
-
auth_basic(auth_header, callback)[source]
Perform Basic authentication using self.settings['pam_realm'].
-
authenticate_redirect()[source]
Informs the browser that this resource requires authentication (status
code 401) which should prompt the browser to reply with credentials.
The browser will be informed that we support Basic auth.
