Root privilege for user

Can anyone please tell how to give root privilege to a normal user in solaris 10?

Temporarily: su or, if installed, sudo
Permanently: No way

This is incorrect, you can actually grant partial or full root privileges (Primary Administrator profile) to any user.
eg:

# usermod -P "Primary Administrator" pludi

After that, that user can run any command with root privileges by prefixing it with "pfexec".

/etc/user_attr file can be modified or you can use RBAC

this question makes me think you are about to have big security problems.
the question inmplys you have the wrong solution to the problem.

why does this "normal user" need root access?

Thanks for replays...

There is no any security problems... I just wanted to know... In windows we can give admin privilege to a user by simply adding to admin group... Was trying the same in Unix..
