Comment # 11 on bug 1209741 from Fabian Vogt

> Since the pam_cifscreds.so issue is directly related to the pam_keyinit.so issue and the fix you are doing, could we please get someone to debug what is going on with pam_cifscreds after this fix is made?

pam_cifscreds' design won't work anymore unless pam_systemd can somehow
transfer the session keyring to systemd --user, which is currently just not
possible. The design of kernel keyrings does not allow it.

Auth is performed by the DM service (sddm) but the keyring used by the DE
session is created by the systemd-user service.
