2. What is a "Pad"
A "Pad" is an on-line web-based collaborative
real-time editor, allowing authors to
simultaneously edit a text document, and see all
of the participants' edits in real-time, with the
ability to display each author's text in their own
color.
Anyone can create a new collaborative
document, known as a "pad". Each pad has its
own URL and anyone who knows this URL can
edit the pad and participate in the associated
chats. Password-protected pads are also
possible. Each participant is identified by a color
and a name.
The software auto-saves the document at regular,
short intervals, but participants can permanently
save specific versions (checkpoints) at any
time. A "time machine" feature allows anyone to
explore the history of the pad, going back in the
past release. The major "milestones" can also be
tagged (or "stared").
A great feature of some pads is that document
can be imported and exported in plain text,
HTML, Open Document, Microsoft Word, or PDF
format.

3. Working with "Pads"
Working with pads is business going social: social networks get us used to be always
updated and connected to our community anytime and anywhere. A pad follow that
mindset and enables you with a simple tool to collaborate with your colleagues and
partners while ensuring the right level of privacy online.
Consider a pad like a clear whiteboard, open a new one and simply start writing an
idea or a challenge. Invite your team, your partners, your external collaborators -no
matter where they are- to share your ideas at the same time.
Let the pad grow with the contribution and the experience of trusted people, every
projects has the right team that are ready to contribute. Review and compare the text
with preview versions, until you'll find the answer and achieve your goal.
Then export it, in your favourite format and share it. For example, write project
documentations with your team through a pad and deliver it in a professional way
using your favorite tool such as Microsoft Word.

6. Etherpad
Etherpad is probably the most famous
pad server implementation: it was born
in 2008 by some Google employees.
Etherpad itself is implemented in
JavaScript, through the Node,js
application environment.
Etherpad was the first web application
of its kind to achieve true real-time
performance,

7. Apache HTTPd
Apache will be handling all data comunication from the external world, playing an important role for securing
communication. In particular, the Apache web server will be performing the following roles:
SSL termination
Reverse proxy to the Etherpad web server on Node.js
Authenticating the user using the SecurePass Web Single Sing-On feature
Limitation of the SecurePass domains/realm for using the pad only within your company or allowing external partners
Translating the user identity into something that Etherpad is able to understand
We will not go in details on how to create a virtual server with the SSL feature.
The configuration has been tested with CentOS 6.

8. Apache configuration
for SecurePass
Follow the instructions on this website:
http://support.secure-pass.net/wiki/index.php/Apache
and ensure you have these values set:

Note that in the website there is also an
upstart configuration file that will work In the Etherpad configuration file
also on CentOS 6. "settings.json" enable
"requireAuthentication" and
