DESCRIPTION</h3></div></div></div><p> The pam_mkhomedir PAM module will create a users home directory if it does not exist when the session begins. This allows users to be present in central database (such as NIS, kerberos or LDAP) without using a distributed file system or pre-creating a large number of directories. The skeleton directory (usually <code class="filename">/etc/skel/</code>) is used to copy default files and also sets a umask for the creation. </p><p> The new users home directory will not be removed after logout of the user. </p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="sag-pam_mkhomedir-options"></a>6.20.2.
