Trying to use cached creds with local users in the passwd file authenticating via kerberos.

I have id_provider set to files and auth_provider set to krb5(AD DC). Online authentication works fine however when I disconnect the network authentication fails. The computer is not joined to a domain, I am only leveraging the domain/realm for authentication purposes

Relevant entries

[pam]

offline_credentials_expiration = 7

[domain]

cache_credentials=true

account_cache_expiration=8

id_provider=files

auth_provider=krb5

krb5_server=srva.example.com

krb5_kpasswd=srva.example.com

krb5_realm=EXAMPLE.COM

dns_discovery_domain=EXAMPLE.COM

krb5_store_password_if_offline=true

Is this a supported configuration for offline logins with cached credentials?

Thanks
