pam_winbind.conf is the configuration file for the pam_winbind PAM
module. See
<a class="citerefentry" href="pam_winbind.8.html"><span class="citerefentry"><span class="refentrytitle">pam_winbind</span>(8)</span></a>
for further details.
</p></div><div class="refsect1" lang="en"><a name="id2522921"></a><h2>SYNOPSIS</h2><p>
The pam_winbind.conf configuration file is a classic ini-style
configuration file. There is only one section (global) where
various options are defined.
</p></div><div class="refsect1" lang="en"><a name="id2522934"></a><h2>OPTIONS</h2><p>
pam_winbind supports several options which can either be set in
the PAM configuration files or in the pam_winbind configuration
file situated at
<code class="filename">/etc/security/pam_winbind.conf</code>. Options
from the PAM configuration file take precedence to those from
the pam_winbind.conf configuration file.
</p><div class="variablelist"><dl><dt><span class="term">debug = yes|no</span></dt><dd><p>Gives debugging output to syslog. Defaults to "no".</p></dd><dt><span class="term">debug_state = yes|no</span></dt><dd><p>Gives detailed PAM state debugging output to syslog. Defaults to "no".</p></dd><dt><span class="term">require_membership_of = [SID or NAME]</span></dt><dd><p>
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: <em class="parameter"><code>MYDOMAIN\\mygroup</code></em> or
<em class="parameter"><code>MYDOMAIN\\myuser</code></em>. 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 <code class="literal">wbinfo --user-sids=SID</code>. This setting is empty by default.
</p></dd><dt><span class="term">try_first_pass = yes|no</span></dt><dd><p>
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. If a primary password is not valid, PAM will prompt for a password.
Default to "no".
</p></dd><dt><span class="term">krb5_auth = yes|no</span></dt><dd><p>
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
<em class="parameter"><code>winbind refresh tickets</code></em>, winbind will
keep your Ticket Granting Ticket (TGT) uptodate by refreshing
it whenever necessary. Defaults to "no".
</p></dd><dt><span class="term">krb5_ccache_type = [type]</span></dt><dd><p>
When pam_winbind is configured to try kerberos authentication
by enabling the <em class="parameter"><code>krb5_auth</code></em> 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:
<em class="parameter"><code>FILE</code></em>. 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. This setting is empty by default.
</p></dd><dt><span class="term">cached_login = yes|no</span></dt><dd><p>
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. Defaults to "no".
</p></dd><dt><span class="term">silent = yes|no</span></dt><dd><p>
Do not emit any messages. Defaults to "no".
</p></dd><dt><span class="term">mkhomedir = yes|no</span></dt><dd><p>
Create homedirectory for a user on-the-fly, option is valid in
PAM session block. Defaults to "no".
</p></dd><dt><span class="term">warn_pwd_expire = days</span></dt><dd><p>
Defines number of days before pam_winbind starts to warn about passwords that are
going to expire. Defaults to 14 days.
