How to list security policy of Red Hat Linux, specifically need password expiration and grace period thereof

I am running Red Hat Enterprise Linux Server release 5.2 and it has a security policy that expires passwords after 90 days. I want to find out specifically what the grace period is (if any) and generally how to list all of the terms of the security policy.
Thank you,

Thanks for the quick reply. Here are my results

ast password change                                    : Nov 11, 2010
Password expires                                        : Feb 09, 2011
Password inactive                                       : Feb 09, 2011
Account expires                                         : never
Minimum number of days between password change          : 0
Maximum number of days between password change          : 90
Number of days of warning before password expires       : 5

I interpret this as meaning that if I don't change my password by Feb 09, 2011 I will be locked out and have to get help from the system administrator. At that point what does the administrator do? Is there a command to reactivate the user so they can log in and change their own password?
As far as I recall you will not be able to login after this date without changing your password.  

I don't believe that it makes your account inactive.

The account expires value would be the one that you would be concerned about in that case.

The super-user could re-activate your password simply by changing it with the passwd command.

GDPR? That's a regulation for the European Union. But, if you collect data from customers or employees within the EU, then you need to know about GDPR and make sure your organization is compliant by May 2018. Check out our preparation checklist to make sure you're on track today!

you can change the password on behalf of the use by passwd.
Or the chage command can be used to (re)set the last password date to something so it is still valid for few days.

Thanks experts ... OK so the system has a 90 day expiration so the following command

chage -d `date +"%Y-%m-%d" -d -89days` THE_USER

will set the user's last password change to 89 days ago and they can log in today and change their password with passwd. If they don't do it today they are locked out again. Perfect.
