mxnodesecurity

[BLETARD Philippe]

Hello,
I've defined some custom commands in HP SIM that must be run as user hpsim, hpsim2 or root...
I've modified the xml definition file for each of them ( field)...
Now my question; these commands will be run via SSH, so for each user, I've an SSH access (running ok), and I've seen that there is the "./mxnodesecurity" that should help me to do what I want...
So, what I've done on the CMS:

I've typed :
./mxnodesecurity -a -p ssh -c hpsim:apasswd -n mymachine
./mxnodesecurity -a -p ssh -c hpsim2:apasswd -n mymachine
./mxnodesecurity -a -p ssh -c root:apasswd -n mymachine

But seems that you can only use this to authorize one user because when I type:
./mxnodesecurity -l -p ssh -n mymachine

I see:

TARGET NODE PROTOCOL NAME PASSWORD
mymachine ssh root ********

So I'm getting a 'SShAuthentication failure' for the commands which should be run as hpsim or hpsim2
I suppose there's an easy way of doing this ?
