Ok I apologize in advance for what is probably a simple question.
I am running Suse Linux 9.3 and am trying understand a specific behavior in regards to password policy management.
From a vanilla install of Suse 9.3 I opened Yast and created a new user in the "edit and create users" tool. I noticed that there were no restrictions, warnings, or expirations applied to the account's password so I opened up the "Security Settings" configuration tool and setup some basic password policies (length, expiration, expiration warnings). Now for every new user I create, they seem to have these settings applied. However, making this configuration change did not apply to accounts created previously.
Why is this?
Are there any good documents that explain what is being modified (config files) by these tools in Yast? I did some searching but can not seem to find a good concise explanation.
Thanks in advance.
