Got it. For the new users, do I have to run "kadmin: modprinc -expire "180 days" newprinc" or will the pwexpire field be set when the account is created?

The KDC only pays attention to the pwexpire field on the principal entries; it doesn't look at the policy. The policy is applied by kadmind (or kadmin.local) when passwords are changed, and sets the pwexpire field on the principals.
