In this tutorial we will learn how to use Spring boot and SPNEGO API to implement the kerberos or integrated authentication. Kerberos is developed by Massachusetts Institute of Technology (MIT) which is used to authenticate between trusted services using KDC tickets. For example email client, HR portal or employee portal in a corporate network where employee doesn't need to provide their user id & password to access these application in the same domain. Once they are logged in to their machine, they can access such services/application with kerberos authentication. I am using MAC OS X to demonstrate the kerberos authentication. I have used the same machine to configure and run the application backed with kerberos authentication and my KDC database & application reside on the same machine. Setting up kerberos  First of all we need to setup kerberos where we will configure the database, create user principals, create policies and keytabs. We need to create our applicatio...

Kerberos in MAC OS X Kerberos authentication allows the computers in same domain network to authenticate certain services with prompting the user for credentials. MAC OS X comes with Heimdal Kerberos which is an alternate implementation of the kerberos and uses LDAP as identity management database. Here we are going to learn how to setup a kerberos on MAC OS X which we will configure latter in our application. Installing Kerberos In MAC we can use Homebrew for installing any software package. Homebrew makes it very easy to install the kerberos by just executing a simple command as given below. brew install krb5 Once installation is complete, we need to set the below export commands in user's profile which will make the kerberos utility commands and compiler available to execute from anywhere. Open user's bash profile: vi ~/.bash_profile Add below lines: export PATH=/usr/local/opt/krb5/bin:$PATH export PATH=/usr/local/opt/krb5/sbin:$PATH export LDFLAGS=...
