You can add a warning to the file (based on your error, I am giving the
file path):
/usr/lib64/python2.7/site-packages/sagenb/data/sage/html/login.html
Find the lines
<div id="sign-in-box">
<h2>Sign into the Sage Notebook v{{ sage_version }}</h2>
and append the following warning below it
<span style="color: red;">Note that the user name is case sensitive.</span>
You can also modify the lines:
{% if username_error %}
<span style="color:red">{{ gettext('Error') }}: </span>{{
gettext('Username is not in the system') }}
and modify the error to be like
gettext('Username is not in the system. Note that the username is case
sensitive')
