        pam_winbind - PAM module for Winbind


        This tool is part of the samba(7) suite.
        pam_winbind is a PAM module that can authenticate users against the
        local domain by talking to the Winbind daemon.


        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 configuration file.
            Gives debugging output to syslog.
            Gives detailed PAM state debugging output to syslog.
        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.
            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
            Set the new password to the one provided by the previously stacked
            password module. If this option is not set pam_winbind will ask the
            user for the new password.
            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.
            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.
            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.
            Do not emit any messages.
            Create homedirectory for a user on-the-fly, option is valid in PAM
            session block.
            Defines number of days before pam_winbind starts to warn about
            passwords that are going to expire. Defaults to 14 days.

        The original Samba software and related utilities were created by
        Andrew Tridgell. Samba is now developed by the Samba Team as an Open
        Source project similar to the way the Linux kernel is developed.
