Password Authorization Number on HP-UX11iv2

[ballans]

Hello all,
I'm running now on a HP-UX11iv2 server (trusted system).
Before, when I was a HP-UX 10.20 system (also trusted system), when I created a new account, the system generated a PAN (Password Authorization Number) for the initial user's password. This is means that the password was composed only with numbers (like 281 for example).
With my new server, I don't know how to configure the system to generate a number in place of a random word...I put the same parameters on the "system trusted policies" of my user templates, but it generates a password with letters...

Do I have to configure an option in another place to do that ? I find this PAN very useful...

Thanks in advance for your help
