assign user to access root owned files
 

Hi,

How to assign normal user to read/access files that owned by root.
These files can only be acceseds by user only which are owned by root.
eg.

-rw------- 1 root root 421 Jul 27 13:53 smbpasswd

You can't with those permissions. Either grant sudo access or change the permissions for a group to have read access and add such user to that group.
