Hi,

No in the nsswitch.conf file i have modified it to ldap, and my /etc/sudoers
file is also blank.

The only exception i did is i created a group as sysadmin assign the sudo
rules and put the user "bob" in that group.
I will add the debug setting tomorrow, and will see why its permitting to
use the command.

Thanks for your help.

Regards,
Neo
