SSO for SAPGUI on HP-UX

SSO for SAPGUI using Kerberos
SAP has some great documentation on how to get SAPGUI to do SSO via 
Kerberos.  However, this documentation all deals with windows 
application servers.  Without purchasing a package, can I get this to 
work with HP-UX 11.23?

Here is an example of the SAP windows centric documentation:
