I have never had this problem in a lab environment where my OES SP1 Linux
server was the only server in the Tree I created during the install. See
OES SP2 Lab Guide, this is what I used for my test.

But, when I try to install the server into my production Tree my iManager
on the Linux server is "missing" several of the key functions. For
instance Lum Management doesn't have LUM enable users or LUM enable
groups listed under it. I've installed and updated all of the Roles and
Tasks modules I have available, but still don't have the options I need
to LUM enable users and groups.

I was planning on making this Linux server a file server with a NSS data
volume and security file permissions managed by eDirectory.

Any help for a beginning OES Linux user would be great.
