Well, you need to store the credentials /somewhere/...so if the credential storage is full, the only remaining thing is to fall back to cached passwords. Which, if they are available (through cache_credentials=True in sssd.conf) is what I'd expect to happen. If that doesn't happen, please post your sssd logs.. _______________________________________________ FreeIPA-users mailing list -- email@example.com To unsubscribe send an email to freeipa-users-le...@lists.fedorahosted.org
