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....
