LEAP Web
---------------------
The LEAP Web App provides the following functions:
* User registration and management
* Help tickets
* Client certificate renewal
* Webfinger access to user’s public keys
* Email aliases and forwarding
* Localized and Customizable documentation
Written in: Ruby, Rails.
The Web App communicates with:
* CouchDB is used for all data storage.
* Web browsers of users accessing the user interface in order to edit their settings or fill out help tickets. Additionally, admins may delete users.
* LEAP Clients access the web app’s REST API in order to register new users, authenticate existing ones, and renew client certificates.
* tokens are stored upon successful authentication to allow the client to authenticate against other services
LEAP Web is provisioned and run as part of the overall [LEAP platform](https://leap.se/en/docs/platform).

* DEVELOP -- for developer notes.
* CUSTOM -- how to customize.

Installation
---------------------------
Typically, this application is installed automatically as part of the
LEAP Platform. To install it manually for testing or development, follow
these instructions:
### Install system requirements
You'll need git, ruby (2.1.5), couchdb and bundler installed.
On a recent debian based distribution run
sudo apt install git ruby couchdb bundler
For other operation systems please lookup the install instructions of these
tools.
### Download source
We host our own git repository. In order to create a local clone run
git clone --recursive git://leap.se/leap_web
The repo is mirrored on github and we accept pull requests there:
https://github.com/leapcode/leap_web
### Install required ruby libraries
cd leap_web
bundle --binstubs
Typically, you run ``bundle`` as a normal user and it will ask you for a
sudo password when it is time to install the required gems. If you don't
have sudo, run ``bundle`` as root.
### Installation for development purposes
Please see `doc/DEVELOP.md` for details about installing
leap_web for development purposes.
Configuration for Production
----------------------------
The configuration file `config/defaults.yml` provides good defaults for
most values. You can override these defaults by creating a file
`config/config.yml`.
There are a few values you should make sure to modify:
production:
admins: ["myusername","otherusername"]
domain: example.net
force_ssl: true
secret_token: "4be2f60fafaf615bd4a13b96bfccf2c2c905898dad34"
client_ca_key: "./test/files/ca.key"
client_ca_cert: "./test/files/ca.key"
ca_key_password: nil
* `admins` is an array of usernames that are granted special admin
privilege.
* `domain` is your fully qualified domain name.
* `force_ssl`, if set to true, will require secure cookies and turn on
HSTS. Don't do this if you are using a self-signed server certificate.
* `secret_token`, used for cookie security, you can create one with
`rake secret`. Should be at least 30 characters.
* `client_ca_key`, the private key of the CA used to generate client
certificates.
* `client_ca_cert`, the public certificate the CA used to generate client
certificates.
* `ca_key_password`, used to unlock the client_ca_key, if needed.
Running
-----------------------------
To run leap_web:
cd leap_web
bin/rake db:rotate
bin/rake db:migrate
bin/rails server
Then open http://localhost:3000 in your web browser.
When running in development mode, you can login with administrative
powers by creating an account with username 'staff', 'blue', or 'red'
(configured in config/default.yml).
To peruse the database, visit http://localhost:5984/_utils/
The task `db:rotate` must come before `db:migrate`, in order to assure that
the special rotating databases get created.
Do not run the normal CouchRest task 'couchrest:migrate'. Instead, use
'db:rotate' since the latter will correctly use the couchdb.admin.yml file.
Testing
--------------------------------
To run all tests
bin/rake RAILS_ENV=test db:rotate # if not already run
bin/rake RAILS_ENV=test db:migrate # if not already run
bin/rake test
To run an individual test:
rake test TEST=certs/test/unit/client_certificate_test.rb
or
ruby -Itest certs/test/unit/client_certificate_test.rb
Known problems
---------------------------
* Client certificates are generated without a CSR. The problem is that
this makes the web application extremely vulnerable to denial of
service attacks. This is not an issue unless the provider enables the
possibility of anonymously fetching a client certificate without
authenticating first.
* By its very nature, the user database is vulnerable to enumeration
attacks. These are very hard to prevent, because our protocol is
designed to allow query of a user database via proxy in order to
provide network perspective.
