I see I can disable the ZCM user login as discussed in the following documentation:

Novell Documentation

If I choose to disable the "user management" on the Agent, does that do the same thing? With User Management disabled, what else does that prevent?

I am not assigning ANY bundles or policies to users - only to workstations. I do have a dynamic local user (dlu) policy assigned to workstations so I must have "User Source" configured... which I do, but certain locations are not in the user source, but are in the Zen Zone - so.... as soon as I configured "User Source" those "branch office" users started receiving the second Zen login after their Novell Client Login. Disabling "User Management" seems to have stopped the 2nd login. Anyone see any problems I might have by doing this? Thanks!
