The filer was looking for a Windows user named "www" so it could look up
its SID and determine what permissions the UNIX user "www" were granted
in the NTFS ACL.
If you don't like mixed-mode qtrees, create a Windows user named "www"
and give it the appropriate permissions in the NTFS ACL to do what it
needs to do (read-only?). Or put a hard mapping in your filers
/etc/usermap.cfg to point UNIX user "www" at an pre-existing NTFS
service account.

Subject: NFS export from within a CIFS share
Had an interesting one today:
We created a CIFS share called "public" to create a department wide
storage area for a project we've got going on. A web developer was
editing HTML in a subfolder there and wanted it published for users to
view. So I NFS mounted it to a test (SUN) webserver exporting it on the
filer as:
/vol/sysvol0/public/html_files
My Unix guy who config'd Apache on the test webserver created a local
user "www" to run Apache. The filer complained when you hit the webpage
generating reads of the "html_files" dir by Apache saying UID 80 NOT
MAPPED. (UID 80 is the www users UID on the webserver). The filer was
expecting CIFS users athentication of an NFS mount!
So you can't NFS export CIFS share folders I found out...!!!???
I ended up creating a (mixed) qtree which is a CIFS share *and* NFS
mount and all is fine....
I thought that was an interesting problem and thought I'd share it....
