<title>DESCRIPTION</title>
<para>
pam_motd is a PAM module that can be used to display
arbitrary motd (message of the day) files after a successful
login. By default the <filename>/etc/motd</filename> file is
shown. The message size is limited to 64KB.

When no options are given, the default is to display both
<filename>/etc/motd</filename> and the contents of
<filename>/etc/motd.d</filename>. Specifying either option (or both)
will disable this default behavior.
