did you mean that in order to apply quota i have to implement it in
samba config file and on mount point also.
only applying quota on mount point will not work, is that what you mean?
can you please guide me to some proper step by step example?

no i can not do that. actually i am the admin and network engineer at
the same time i am a one man army doing everything :P anyways. our
users are very irresponsible i know they will dump their personal data
to their personal folder they think personal folder on fileserver
means storage for any thing ;) so better telling and teaching every
one quota is a best solution in my case

thanks for sharing you experience, but i was reading an article the
guy was suggesting to use a virtual file system image. so that how big
you create the file your quota will be limited to that image size no
matter whoever is accessing that share. but definitely this is a work
around.
any suggestion on that?
