krbPrincipalExpiration and ssh keys

[Jim Kinney]

It seems if valid ssh keys exist, the expired account status doesn't block login with ssh keys. Any operation that touches a password is blocking. 
Is there a pam setting in sshd that needs tweaking to deny access if account is expired?

You may want to cross post this on sssd-users.

Hi,

in general SSSD can handle this case with 'access_provider = ldap' and
pwd_expire_policy_reject, pwd_expire_policy_warn or
pwd_expire_policy_renew in 'ldap_access_order', see man sssd-ldap for
details.

Unfortunately this removes the HBAC features of 'access_provider = ipa'.
We are currently working on making the ldap features available in ipa as
well, see https://github.com/SSSD/sssd/issues/5080 and the related
pull-request.
