SAFARI OS X MAC Corporate Single Sign On using Windows Credentials SSO LDAP Kerberos

Kerberos is built into Mac OS X as well, but isn't as simple to use and configure with Chrome and FireFox as it is with Explorer on a Windows workstation.
You need to do two things before you can use Kerberos for authentication in Chrome/FireFox:

1. Create a Kerberos ticket with the Ticket Viewer application (/System/Library/CoreServices/Ticket Viewer)  
2. OR via the command line (kinit username@example.com, then enter your password). See this article for more detailed instructions.
