Yes it does. We use it to provide magic symlinks which point to different
places for different people. So we have for example a symlink called "ux"
and it points to "/servers/USERNAME/our-server/ux" where USERNAME is the
name from /etc/passwd matching the user id of the user accessing the
symlink. So in documentaion and in stupid programs which require
hardcoding of path we specify "/ux" to find the shared space but in
reality this is a different local directory for every user. (To complete
the picture the different local directories are actually the same remote
directory but mounted with access permissions for each user separately
using ncpfs.)
