| 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>. |

|---|
| 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 | |
|---|
| 38 | </p></dd><dt><span class="term">krb5_ccache_type=[type]</span></dt><dd><p> |
|---|
| 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. |
