2        pam_winbind is a PAM module that can authenticate users against the local domain by talking to the Winbind daemon.
3        </p></div><div class="refsect1" lang="en"><a name="id230771"></a><h2>OPTIONS</h2><p>
4       
5                pam_winbind supports several options which can either be set in
6                the PAM configuration files or in the pam_winbind configuration
7                file situated at
8                <code class="filename">/etc/security/pam_winbind.conf</code>. Options
9                from the PAM configuration file take precedence to those from
10                the configuration file.
11
12                </p><div class="variablelist"><dl><dt><span class="term">debug</span></dt><dd><p>Gives debugging output to syslog.</p></dd><dt><span class="term">require_membership_of=[SID or NAME]</span></dt><dd><p>
13                If this option is set, pam_winbind will only succeed if the user is a member of the given SID or NAME. A SID
14                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
15                SID. That name must have the form: <em class="parameter"><code>MYDOMAIN\\mygroup</code></em> or
16                <em class="parameter"><code>MYDOMAIN\\myuser</code></em>.  pam_winbind will, in that case, lookup the SID internally. Note that
17                NAME may not contain any spaces. It is thus recommended to only use SIDs. You can verify the list of SIDs a
18                user is a member of with <span><strong class="command">wbinfo --user-sids=SID</strong></span>.
19                </p></dd><dt><span class="term">try_first_pass</span></dt><dd><p></p></dd><dt><span class="term">use_first_pass</span></dt><dd><p>
20                By default, pam_winbind tries to get the authentication token from a previous module. If no token is available
21                it asks the user for the old password. With this option, pam_winbind aborts with an error if no authentication
22                token from a previous module is available.
23                </p></dd><dt><span class="term">use_authtok</span></dt><dd><p>
24                Set the new password to the one provided by the previously stacked password module. If this option is not set
25                pam_winbind will ask the user for the new password.
26                </p></dd><dt><span class="term">krb5_auth</span></dt><dd><p>
27
28                pam_winbind can authenticate using Kerberos when winbindd is
29                talking to an Active Directory domain controller. Kerberos
30                authentication must be enabled with this parameter. When
31                Kerberos authentication can not succeed (e.g. due to clock
32                skew), winbindd will fallback to samlogon authentication over
33                MSRPC. When this parameter is used in conjunction with
34                <em class="parameter"><code>winbind refresh tickets</code></em>, winbind will
35                keep your Ticket Granting Ticket (TGT) uptodate by refreshing
36                it whenever necessary.
37

39               
40                When pam_winbind is configured to try kerberos authentication
41                by enabling the <em class="parameter"><code>krb5_auth</code></em> option, it can
42                store the retrieved Ticket Granting Ticket (TGT) in a
43                credential cache. The type of credential cache can be set with
44                this option. Currently the only supported value is:
45                <em class="parameter"><code>FILE</code></em>. In that case a credential cache in
46                the form of /tmp/krb5cc_UID will be created, where UID is
47                replaced with the numeric user id.  Leave empty to just do
48                kerberos authentication without having a ticket cache after the
49                logon has succeeded.
50
51                </p></dd><dt><span class="term">cached_login</span></dt><dd><p>
52                Winbind allows to logon using cached credentials when <em class="parameter"><code>winbind offline logon</code></em> is enabled. To use this feature from the PAM module this option must be set.

60        the Samba Team as an Open Source project similar to the way the Linux kernel is developed.
