Hi all,
In my server we login with a common userid/passwd. There is a file created with this Id and everyone has acess to modify the contents. We need to restrict this in such a way that when a person tries change certain this in the file he should be restricted in doing it.
Basically It should ask for a passwd before saving the file so only few within the same group will have control to do so...
Note: We cannot use root passwd. We cannot change the perm of file as every user logins with the same user/passwd they can also change the perm...
