We use it here along with the Kanaka client for accessing servers and enable Mobile Managed accounts. Everything seems to be working fine. We have some issues with the Kanaka service stopping on the servers, but they are fairly our of date with patches.
We've been using Novell in our school district since the late 90's, with no real issues. Though we are now phasing it out with a move to Google Apps and phasing out home directories with going to a 1:1 Mac rollout.
Any particular questions?
