Enable winbind for system authentication
========================================

Selecting this profile will enable Samba's winbind as the source of identity
and authentication providers.

The Samba standard Windows interoperability suite of utilities allows Linux
systems to join an Active Directory environment by making them appear to be
Windows clients. As a means of systems integration, Samba allows a Linux
client to join an Active Directory Kerberos realm and to use Active Directory
as its identity store.

Winbind is a component of the Samba suite to provide unified logon. It uses a
UNIX implementation of Microsoft RPC calls, Pluggable Authentication
Modules (PAMs), and the Name Service Switch (NSS) to allow Windows domain
users to appear and operate as UNIX users on a UNIX system.

WINBIND CONFIGURATION
---------------------

Authselect does not touch winbind's configuration. Please, read winbind's
documentation to see how to configure it manually. Only local users will be
available on the system if there is no existing winbind configuration.

AVAILABLE OPTIONAL FEATURES
---------------------------

with-faillock::
    Enable account locking in case of too many consecutive
    authentication failures.

with-mkhomedir::
    Enable automatic creation of home directories for users on their
    first login.

with-fingerprint::
    Enable authentication with fingerprint reader through *pam_fprintd*.

with-pam-gnome-keyring::
    Enable pam-gnome-keyring support.

with-pam-u2f::
    Enable authentication via u2f dongle through *pam_u2f*.

with-pam-u2f-2fa::
    Enable 2nd factor authentication via u2f dongle through *pam_u2f*.

without-pam-u2f-nouserok::
    Module argument nouserok is omitted if also with-pam-u2f-2fa is used.
    *WARNING*: Omitting nouserok argument means that users without pam-u2f
    authentication configured will not be able to log in *INCLUDING* root.
    Make sure you are able to log in before losing root privileges.

with-krb5::
    Enable Kerberos authentication with *pam_winbind*.

with-silent-lastlog::
    Do not produce pam_lastlog message during login.

with-pamaccess::
    Check access.conf during account authorization.

with-pwhistory::
    Enable pam_pwhistory module for local users.

without-nullok::
    Do not add nullok parameter to pam_unix.

DISABLE SPECIFIC NSSWITCH DATABASES
-----------------------------------

Normally, nsswitch databases set by the profile overwrites values set in
user-nsswitch.conf. The following options can force authselect to
ignore value set by the profile and use the one set in user-nsswitch.conf
instead.

with-custom-passwd::
Ignore "passwd" database set by the profile.

with-custom-group::
Ignore "group" database set by the profile.

EXAMPLES
--------
* Enable winbind with no additional modules

* Enable winbind and create home directories for users on their first login
