# Omniauth::Strategies::Kerberos
[](https://travis-ci.org/jgraichen/omniauth-kerberos)

**omniauth-kerberos** is a simple [OmniAuth](https://github.com/intridea/omniauth) strategy to authenticate using a Kerberos server. **omniauth-kerberos** can be used as an authenticator for [OmniAuth MultiPassword](https://github.com/jgraichen/omniauth-multipassword).
## Installation
Add this line to your application's Gemfile:
gem 'omniauth-kerberos'
And then execute:
$ bundle
Or install it yourself as:
$ gem install omniauth-kerberos
Kerberos development headers are required to build dependencies.
On Debian try:
$ sudo apt-get install libkrb5-dev
## Usage
Use **omniauth-kerberos** like any other OmniAuth strategy:
```ruby
Rails.application.config.middleware.use OmniAuth::Builder do
provider :kerberos
end
```
You still need to configure your system for Kerberos usage like specifying realms. If you has your own login form you can specify the fields to use:
```ruby
Rails.application.config.middleware.use OmniAuth::Builder do
provider :kerberos, :fields => [ :login, :pwd ]
end
```
## Options
** title **
The title text shown on default login form.
(default: `"Restricted Access"`)
** fields **
The request parameter names to fetch username and password.
(default: `[ "username", "password" ]`)
