    Hi All.

    I have a process on my iMac (core i7 quad, 16 GB Ram) thats called KRB5KDC. It uses 100 % of my processor, and 2,8GB Ram, All the time - Even just after i booted up. This makes the computer pretty useless as you can imagine.

    After googling and mRoogling around i found out that the process belongs to Kerberos - some sort of network authentication protocol - i dont know anything about that, but it shouldnt use 100 % processor power.

    Any help would be greatly appreciated, since applecare couldnt do anything but offer a hardware repair - strange solution for a software problem...

    KBR5KDC is used to authenticate via Kerberos 5 to a domain controller.

    Try going to System Preferences, Accounts, and Login Options (at the bottom of the user list). There should be an button to [Join...] a Network Account Server. Click Join... and then click [Open Directory Utility...] This opens the Directory Utility. In this utility, you may have enabled "Active Directory", turn it off. You can also remove the "Network Account Server" if it is configured.

    Not sure if it will work, but give it a try.
