SSO using Kerberos for AIX - How?

Hi,

I need to setup SSO in my SAP systems, using Kerberos, so that users from Windows terminals can login to a system using SAPGUI without giving a user/password.

I know it is possible because I have seen it somewhere in the past.

However, despite searching on SAP Help, I still cannot find the steps for it. I checked the following links, but they all talked about setup where SAP system is on Windows platform, but I cant find anything for AIX (or any other Unix/Linux flavor).

Please help.
