We had been using amd instead of autofs on a large server, with possibly 100 - 200 concurrent login sessions.
With autofs, each home directory for a logged in user would be a separate mount point. We found that things
started to get ugly, when the number of mount points grew to a number somewhat less than 256, maybe 200
to 220. Using instead static mounts from the file servers, and then using amd to manage symlinks, via map
entries for /home of the form
     username fs:=/directory/path;type:=link
keeps the number of nfs mounts down to the number of static mounts.

We have been using autofs on all our other linux boxes (Ubuntu and Fedora). But due to this issue
we had been using amd on our main instructional server, now running Ubuntu.

Have other people had success with using autofs for /home, with large numbers of concurrent logins?
With more than say 256 nfs mount points?
