NAME
       pam_winbind.conf - Configuration file of PAM module for Winbind

DESCRIPTION
       This configuration file is part of the samba(7) suite.

       pam_winbind.conf is the configuration file for the pam_winbind PAM module. See pam_winbind(8) for further details.

SYNOPSIS
       The pam_winbind.conf configuration file is a classic ini-style configuration file. There is only one section (global)
       where various options are defined.

OPTIONS
       pam_winbind supports several options which can either be set in the PAM configuration files or in the pam_winbind
       configuration file situated at /etc/security/pam_winbind.conf. Options from the PAM configuration file take precedence to
       those from the pam_winbind.conf configuration file.

       debug = yes|no
           Gives debugging output to syslog. Defaults to "no".

       debug_state = yes|no
           Gives detailed PAM state debugging output to syslog. Defaults to "no".

       require_membership_of = [SID or NAME]
           If this option is set, pam_winbind will only succeed if the user is a member of the given SID or NAME. A SID can be
           either a group-SID, an alias-SID or even an user-SID. It is also possible to give a NAME instead of the SID. That
           name must have the form: MYDOMAIN\\mygroup or MYDOMAIN\\myuser. pam_winbind will, in that case, lookup the SID
           internally. Note that NAME may not contain any spaces. It is thus recommended to only use SIDs. You can verify the
           list of SIDs a user is a member of with wbinfo --user-sids=SID. This setting is empty by default.

       try_first_pass = yes|no
           By default, pam_winbind tries to get the authentication token from a previous module. If no token is available it
           asks the user for the old password. With this option, pam_winbind aborts with an error if no authentication token
           from a previous module is available. If a primary password is not valid, PAM will prompt for a password. Default to
           "no".

       krb5_auth = yes|no
           pam_winbind can authenticate using Kerberos when winbindd is talking to an Active Directory domain controller.
           Kerberos authentication must be enabled with this parameter. When Kerberos authentication can not succeed (e.g. due
           to clock skew), winbindd will fallback to samlogon authentication over MSRPC. When this parameter is used in
           conjunction with winbind refresh tickets, winbind will keep your Ticket Granting Ticket (TGT) uptodate by refreshing
           it whenever necessary. Defaults to "no".

       krb5_ccache_type = [type]
           When pam_winbind is configured to try kerberos authentication by enabling the krb5_auth option, it can store the
           retrieved Ticket Granting Ticket (TGT) in a credential cache. The type of credential cache can be set with this
           option. Currently the only supported value is: FILE. In that case a credential cache in the form of /tmp/krb5cc_UID
           will be created, where UID is replaced with the numeric user id. Leave empty to just do kerberos authentication
           without having a ticket cache after the logon has succeeded. This setting is empty by default.

       cached_login = yes|no
           Winbind allows to logon using cached credentials when winbind offline logon is enabled. To use this feature from the
           PAM module this option must be set. Defaults to "no".

       silent = yes|no
           Do not emit any messages. Defaults to "no".

       mkhomedir = yes|no
           Create homedirectory for a user on-the-fly, option is valid in PAM session block. Defaults to "no".

       warn_pwd_expire = days
           Defines number of days before pam_winbind starts to warn about passwords that are going to expire. Defaults to 14
           days.
