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 situ-
       ated 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,
	  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: MYDOMAINmygroup or
	  MYDOMAINmyuser. pam_winbind will, in that case, lookup the SID internally. Note that NAME may not contain any spaces. It is thus recom-
	  mended 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 Grant-
	  ing 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.
