I have a client who is complaining that after I migrated to NSS on Linux
from NSS on NetWare, that he has upperlower case issue with Eclipse on
Windows XP running from the NSS volume as he did before.

Old Server Volume Loaded name spaces:DOS, MAC, NFS, LONG

New Server is just long, as recommended by the NSS manual.
Status: online mounted NSS Long "user quotas" "directory quotas"

What are the implications of added the DOS namespace?
Would it run into the same issues as adding NFS namespace and poor
performance? As I think the missing DOS namespace is the issue??(I could
be wrong)
