limit root logins

[Rick Garland]

Hi all:

Dealing with RedHat versions 7 and above.

I want to be able to limit which accts can su to the root user. On HP you can use the /etc/default/security file, in Solaris can be a member of the wheel group.

How can I specifiy that only a certain set of accounts can become the root user?

Many thanks!

Apparently you can do this by tailoring the

/etc/pam.d/su file !

I have not done this but a type of the file say's you can put people allow in a specific group

man pam.d is very long !

I am reading this now.

Hope It help, always nice to start a new invetigation.. thanks,
