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.
