What is wrong with permissions in centos 6?

Question

linux

Hello!
There is a server on CentOS6, CAD is installed on it, users connect to it using vnc. It is required to make sure that users store their projects on Win Share.
Added users on the CentOS6 server to the sapr group.
Did the following:

mount -a //server/sapr /media/sapr/ -o username=user,password=pass
chown root:sapr /media/sapr/
chmod -R /media/sapr/

Users see /media/sapr/ but cannot view or write files.
How to fix?

Answer 1

rights to the studio
ls -l / media / sapr

Answer 2

With the help of chmod, transfer rights to the group, otherwise somehow "-R" and that's it
Well, or look at the output, I think you'll understand
ls -l /media | grep sapr
