NOPASSWORD .... enable single user mode wihch is needed for ACLs
CAUSER     .... Access Control List (A=Allow access, N=Deny access)
NO_HOSTS_EQUIV=1   ... disable UNIX/Linux host equiv. authentication

Commands to start/stop CA agent:

$ sudo /etc/init.d/bab_agent start
$ sudo /etc/init.d/bab_agent stop
