Here at the University of Alberta the Academic Information and Communications Technology department have started using UIDs above the 64K boundary. Since I need to keep my UIDs synchronized with the ones they use and I want to use Scientific Linux do I need to compile a custom kernel to get this functionality? In other words what is the kernel default maximum UID set to? -- Bob Barton <[log in to unmask]> Local Area Administrator (780) 492-5160 564B Chemical & Materials Engineering University of Alberta, Edmonton Alberta, T6G 2G6
