While not home directories we have simply put an entry as for any automounted directory in the /etc/auto_home. Works just like any other server.
archive nas01:/vol/sys/projects scans nas01:/vol/sys/scans
so a typical user could cd to /home/archive.
Note for some reason our vol0 is named sys, but you get the idea. I am assuming you have nfs exports, unix security style etc. already set up.
