26 pam_winbind.conf is the configuration file for the pam_winbind PAM
28 <citerefentry><refentrytitle>pam_winbind</refentrytitle><manvolnum>8</manvolnum></citerefentry>
34 <title>SYNOPSIS</title>
37 The pam_winbind.conf configuration file is a classic ini-style
38 configuration file. There is only one section (global) where
39 various options are defined.
44 <title>OPTIONS</title>
47 pam_winbind supports several options which can either be set in
48 the PAM configuration files or in the pam_winbind configuration
50 <filename>/etc/security/pam_winbind.conf</filename>. Options
51 from the PAM configuration file take precedence to those from
52 the pam_winbind.conf configuration file.
57 <term>debug = yes|no</term>
58 <listitem><para>Gives debugging output to syslog. Defaults to "no".</para></listitem>
62 <term>debug_state = yes|no</term>
63 <listitem><para>Gives detailed PAM state debugging output to syslog. Defaults to "no".</para></listitem>
67 <term>require_membership_of = [SID or NAME]</term>
69 If this option is set, pam_winbind will only succeed if the user is a member of the given SID or NAME. A SID
70 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
71 SID. That name must have the form: <parameter>MYDOMAIN\\mygroup</parameter> or
72 <parameter>MYDOMAIN\\myuser</parameter>. pam_winbind will, in that case, lookup the SID internally. Note that
73 NAME may not contain any spaces. It is thus recommended to only use SIDs. You can verify the list of SIDs a
74 user is a member of with <command>wbinfo --user-sids=SID</command>. This setting is empty by default.
79 <term>try_first_pass = yes|no</term>
81 By default, pam_winbind tries to get the authentication token from a previous module. If no token is available
82 it asks the user for the old password. With this option, pam_winbind aborts with an error if no authentication
83 token from a previous module is available. If a primary password is not valid, PAM will prompt for a password.
89 <term>krb5_auth = yes|no</term>
92 pam_winbind can authenticate using Kerberos when winbindd is
93 talking to an Active Directory domain controller. Kerberos
94 authentication must be enabled with this parameter. When
95 Kerberos authentication can not succeed (e.g. due to clock
96 skew), winbindd will fallback to samlogon authentication over
97 MSRPC. When this parameter is used in conjunction with
98 <parameter>winbind refresh tickets</parameter>, winbind will
99 keep your Ticket Granting Ticket (TGT) uptodate by refreshing
100 it whenever necessary. Defaults to "no".
106 <term>krb5_ccache_type = [type]</term>
109 When pam_winbind is configured to try kerberos authentication
110 by enabling the <parameter>krb5_auth</parameter> option, it can
111 store the retrieved Ticket Granting Ticket (TGT) in a
112 credential cache. The type of credential cache can be set with
113 this option. Currently the only supported value is:
114 <parameter>FILE</parameter>. In that case a credential cache in
115 the form of /tmp/krb5cc_UID will be created, where UID is
116 replaced with the numeric user id. Leave empty to just do
117 kerberos authentication without having a ticket cache after the
118 logon has succeeded. This setting is empty by default.
124 <term>cached_login = yes|no</term>
126 Winbind allows to logon using cached credentials when <parameter>winbind offline logon</parameter> is enabled. To use this feature from the PAM module this option must be set. Defaults to "no".
131 <term>silent = yes|no</term>
133 Do not emit any messages. Defaults to "no".
138 <term>mkhomedir = yes|no</term>
140 Create homedirectory for a user on-the-fly, option is valid in
141 PAM session block. Defaults to "no".
146 <term>warn_pwd_expire = days</term>
148 Defines number of days before pam_winbind starts to warn about passwords that are
149 going to expire. Defaults to 14 days.
