I kept getting a -672 error in NSSMU or iManager while trying to create an NSS pool on my OES 2 server. There was a TID pointing to NETVISION as the problem but I did not have it installed on this server.
I found TID 3544536, that did not point to my error specifically but that resolved it right away.
Type nssAdminInstall -a admin.novell -p novell -o nssAdmin.novell (Specify your own username, password ).
Now this environment was new so you may already have this user in your environment.
Hopefully this helps someone else.
