Description Jakub Hrozek 2018-01-22 20:01:39 UTC

This bug is created as a clone of upstream ticket:
https://pagure.io/SSSD/sssd/issue/3603

After investigating the issue #3602 (https://pagure.io/SSSD/sssd/issue/3602) seems that a similar issue may happen with certificates.

I've talked to @sbose and we agreed on opening this to investigate whether it's the case and then provide a proper fix for this in case a bug is also present.

Steps to reproduce will be added later on when someone starts working on this bug.

Comment 1 Jakub Hrozek 2018-01-22 20:02:52 UTC

Rough steps to reproduce:

- add a certificate to an override of a subdomain user
- request the certificate with the dbus API
- remove the certificate from the override
- request the certificate again

If there are no certificates returned for a sub-domain user from the IPA
server to the client we should make sure they are not present in the
client's cache anymore and remove the whole attribute from the cached user
entry.
