"su" command causes log message, what's it mean?
Every time I execute the su command (to become root) on my home computer, a message is logged in /var/log/secure. The su command succeeds without any error message to the terminal.
I suppose I could get rid of this by putting myself in the wheel group, but
... su: pam_succeed_if: requirement "user ingroup wheel" not met by user "ken"
- Why do I get the message?
- What's the point of griping if it doesn't prevent access?
- Is there any security implication to joining wheel?
- Can I get rid of the message, other than joining wheel?
