If a pre-login banner is required, then the following files must be present for Stratus to use:

$APL/sdi/html/login/banner-large.htm  (for use with the Stratus Web UI and capable mobile devices)
$APL/sdi/html/login/banner-small.htm  (for use with text-limited mobile devices)

Example, copying the DoD banners to be active:

cp -p $APL/sdi/banners/banner-dod-large.htm $APL/sdi/html/login/banner-large.htm
cp -p $APL/sdi/banners/banner-dod-small.htm $APL/sdi/html/login/banner-small.htm
