[sudo-users] issues with sudo -i or sudo -s

Hi Mark

Thanks for the guidance.

I am facing one issue. 

dbaadmin$ sudo -u oracle10 <some_command>, while  executing this command, I would like  the profile of oracle10 to be executed along with the command. It tells me command not found etc. I need to manually execute the profile file. I have multiple oracle versions installed on a single server, require the account profile to be executed along with the sudo -u <oraclex> <command>.  Let me know if I have some solution / workaround.

This gives everyone in group dbaadmin full root access... they sudo to
oracle10, start a shell, and sudo to root ;P
Only the ALL=(oracle10) line should be enough...
dbaadmin$ sudo -u oracle10 <some_command>
is the command your users should use to run something as oracle10

Negations don't work as you would expect... people can make a symlink
to a shell and start that, or they can start vi, and use a
They can write their own script, which runs a shell, and start that.

You should make NOEXEC a default, and !NOEXEC the specific commands
that NEED it.

Second bit doesn't work as expected either...
