"""
AuthConfig class implements system-independent interface to configure
system authentication resources. In Red Hat systems this is done with
authconfig(8) utility.
AuthConfig class is nothing more than a tool to gather configuration options
and execute their processing. These options then converted by an actual implementation
to series of a system calls to appropriate utilities performing real configuration.
IPA *expects* names of AuthConfig's options to follow authconfig(8) naming scheme!
Actual implementation should be done in ipapython/platform/<platform>.py by inheriting from
platform.AuthConfig and redefining __build_args() and execute() methods.
from ipapython.platform import platform
class PlatformAuthConfig(platform.AuthConfig):
def __build_args():
...
def execute():
...
authconfig = PlatformAuthConfig
....
See ipapython/platform/redhat.py for a sample implementation that uses authconfig(8) as its backend.
From IPA code perspective, the authentication configuration should be done with use of ipapython.services.authconfig:
from ipapython import services as ipaservices
auth_config = ipaservices.authconfig()
auth_config.disable("ldap").\
disable("krb5").\
disable("sssd").\
disable("sssdauth").\
disable("mkhomedir").\
add_option("update").\
enable("nis").\
add_parameter("nisdomain","foobar")
auth_config.execute()
If you need to re-use existing AuthConfig instance for multiple runs, make sure to
call 'AuthConfig.reset()' between the runs.
