Dear Group members/list,

Hi.

I would like to know the place where I can find the linux password 
constraints for the various linux flavors. What I mean is the details like 
number of key spaces or the key length, the types of charactors that can be 
used, the restrictions and the number of times the password can be tried if 
not infinite, etc. I am in need of these details very urgently, so please do 
help me on this topic.

The password "mechanism" normally uses Linux-PAM (Pluggable
Authentication Modules) integration. The constraints that you mention
can be implemented with some PAM modules.

See: http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/pam.html

And specifically:

Regards.
