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.
