Drive Mapping on Novell 5.0 server

My Container Login Scripts for my Novell 5.0 and 4.11 servers only ever map to server/SYS. Why is this? The MAP statement in the script is either MAP G: = \\server/sys:folder1 or MAP G: = server_SYS:folder1. I am expecting G: to point to folder1 on the SYS volume of the server. Is this correct, or am I missing something?
