last logged in user

Where can I find the field for a workstation to get the last logged in 
user? I can find mac address and owner and last registered time 
(everytime user logs in) in the workstation base class, but not last 

Hi

The Zen team doesn't publish its schema, but there are sometimes references
to various classes at support.novell.com knowlegebase. Have you looked at
WM:User History or WM: User Name?

Thank you
