A Clojure library for Kerberos authentication. Also includes a Ring middleware function and a Pedestal interceptor for SPNEGO authentication.
An example with Ring and Compojure:
(ns kerberos-spnego.core.handler
(:require [clojure.pprint :refer [pprint]]
[compojure.core :refer :all]
[compojure.route :as route]
[ring.middleware.defaults :refer [wrap-defaults site-defaults]]
[sarnowski.kerberos :as kerberos]
[sarnowski.kerberos.spnego :as spnego]))
(def service-subject (kerberos/create-service-subject
"HTTP/[email protected]"
(kerberos/create-config
{:useKeyTab true
:keyTab "resources/local.keytab"
:principal "HTTP/[email protected]"
:storeKey true
:doNotPrompt true
:debug true
:isInitiator false})))
(defroutes app-routes
(GET "/" r (with-out-str (pprint r)))
(route/not-found "Not Found"))
(def app
(-> app-routes
(wrap-defaults site-defaults)
(spnego/authenticate service-subject)))
To run tests, you need to provide a keytab and credentials for your test KDC.
$ JVM_OPTS="-Dkerberos.principal=HTTP/[email protected]
-Dkerberos.keytab=../local.keytab
[email protected]
-Dkerberos.password=test123" \
lein test
