cobbler.modules.authentication.pam.authenticate(api_handle: CobblerAPI, username: str, password: str) → bool[source]

Validate PAM authentication, returning whether the authentication was successful or not.

Parameters

  • api_handle – Used for resolving the pam service name and getting the Logger.

  • username – The username to log in with.

  • password – The password to log in with.

Returns

True if the given username and password authenticate for the given service. Otherwise False

cobbler.modules.authentication.pam.register() → str[source]

The mandatory Cobbler module registration hook.

8.1.4.1.1.6. cobbler.modules.authentication.passthru module

Authentication module that defers to Apache and trusts what Apache trusts.

cobbler.modules.authentication.passthru.authenticate(api_handle: CobblerAPI, username: str, password: str) → bool[source]

Validate a username/password combo. Uses cobbler_auth_helper

Parameters

  • api_handle – This parameter is not used currently.

  • username – This parameter is not used currently.

  • password – This should be the internal Cobbler secret.

Returns

True if the password is the secret, otherwise false.

8.1.4.1.1.8. Module contents

This module represents all Cobbler methods of authentication. All present modules may be used through the configuration file modules.conf normally found at /etc/cobbler/.

In the following the specification of an authentication module is given:

  1. The name of the only public method - except the generic register() method - must be authenticate

  2. The attributes are - in exactly this order: api_handle, username, password

  3. The username and password both must be of type str.

  4. The api_handle must be the main CobblerAPI instance.

  5. The return value of the module must be a bool.

  6. The method should only return True in case the authentication is successful.

  7. Errors should result in the return of False and a log message to the standard Python logger obtioned via logging.getLogger().

  8. The return value of register() must be authn.

The list of currently known authentication modules is:

  • authentication.configfile

  • authentication.denyall

  • authentication.ldap

  • authentication.pam

  • authentication.passthru

  • authentication.spacewalk
