Changing Kerberos password with PHP

I have a need to create and update user pass开发者_StackOverflowword using Kerberos and my site is PHP. I found a PHP extension which allows this type of interaction, but it is from 2003 and can no longer be compiled due to Kerberos updating since then. Kerberos PHP Extension

I searched for other ways to do this, but I couldn't find any. Does anyone have experience with this?
