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.

  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, a
       alias-SID or even a user-SID. It is also possible to give a NAME
       instead of the SID. That name must have the form: MYDOMAIN\\mygroup
       orMYDOMAIN\\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
       withwinbind 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.
