<para>The argument use_first_pass forces the module to use
a previous stacked modules password and will never prompt
the user - if no password is available or the password is
not appropriate, the user will be denied access.</para>

<para>If specified the user is asked another N times for a
password if authentication fails. Default is 0.</para>
<para>Please note that this option might not work as
expected if the application calling PAM handles the user
dialog on its own. A typical example is

<option>PasswordAuthentication</option>.</para>

<para>If a password reset by root fails, because the corresponding SSSD
provider does not support password resets, an individual message can be
displayed. This message can e.g. contain instructions about how to reset
a password.</para>
<para>The message is read from the file
<filename>pam_sss_pw_reset_message.LOC</filename> where LOC stands for a
locale string returned by <citerefentry>
<refentrytitle>setlocale</refentrytitle><manvolnum>3</manvolnum>
</citerefentry>. If there is no matching file the content of
<filename>pam_sss_pw_reset_message.txt</filename> is displayed. Root
must be the owner of the files and only root may have read and write
permissions while all other users must have only read
permissions.</para>
<para>These files are searched in the directory
<filename>/etc/sssd/customize/DOMAIN_NAME/</filename>. If no matching
file is present a generic message is displayed.</para>
