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">debug_state</span></dt><dd><p>Gives detailed PAM state 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 <code class="literal">wbinfo --user-sids=SID</code>. 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 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.
