[SOLVED] Set password policy per-user using cracklib?

j_h · 10-20-2011, 03:42 AM

Hi,

I'd like to set the minimum length of password differently for normal users and root.

I don't think it's possible to do via YaST (openSUSE settings panel) - 'global' password settings has a min length option, but under user account settings it only gives password ageing options.

Is it possible to do this using cracklib?

See the following link: http://linux.about.com/cs/linux101/g/cracklib.htm
From the link:

Quote:

CrackLib tests passwords to determine whether they match certainsecurity-oriented characteristics, with the purpose of stopping users from choosing passwords that are easy to guess.

Noway,

Thanks for the link, but it doesn't actually answer my question. I already know how to enforce (across-the-board) min length using cracklib.

What I want to know is if there is any way in linux (via cracklib or otherwise) to have different minimum lengths for different users or groups, rather than having one global value.

Thanks in advance if anyone can help me solve this, or at least confirm it's not possible!

AFAIK cracklib nor passwdqc offers that kind of granular control.

I see, thanks for confirming
