Hi, I have searched the archive of these lists and Googled extensively to solve this problem but so far I haven't had any luck. Here is what I'm trying to do: UserA@REALM is to ksu to UserB@REALM without knowing UserBs password. UserB has UserA in .k5login and UserA has aquired its credentials via kinit. Still ksu asks for UserBs password. What am I missing? /Anton
