    <title>DESCRIPTION</title>
    <para>
      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
      <filename>/etc/skel/</filename>) is used to copy default files
      and also sets a umask for the creation.
    </para>
    <para>
      The new users home directory will not be removed after logout
      of the user.
    </para>
