pam_winbind(7)

NAME

       pam_winbind - PAM module for Winbind

DESCRIPTION

       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.

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 configuration file.

       debug
           Gives debugging output to syslog.

       debug_state
           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.

       try_first_pass

       use_first_pass
           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.

       use_authtok
           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.

       krb5_auth
           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.

       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.

       cached_login
           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.

       silent
           Do not emit any messages.
