Right, thats why I said role based access.

the sudo role can contain:


sudoUser: %someusergroup
userGroup: someusergroup

sudoHost: +somehostgroup
hostGroup: somehostgroup
hostGroup: nosudohostgroup

sudoCommand: ALL

memberUid: username

host: hosta
host: hostb
host: hostc

host: hostd
host: hoste
host: hostf

I am not suggesting that the hostgroups or usergroups as they are  
represented in the role should double as both login and escalation  
rights. I define those separately with sudoHost vs hostGroup and  
sudoUser vs userGroup.

However I DO want to utilize the same sets of hostgroups / usergroups  
as they are static containers that define groups of hosts or users.

In this demonstration, username has login and sudo access to hosta,  
hostb, hostc, but it _only_ has login access to hostd, hoste, hostf.

Does this help ease the confusion?
