Hello all,

since some time we have some cases where a sssd login does not work anymore and a service restart is necessary. According to analysis, there is a high disk and CPU usage at that time.

Affected are clients with Ubuntu 20.04 sssd 2.2.3 freeipa 4.8.6

We get the following error messages:

sssd_pam.log [pam] [sss_dp_on_reconnect] (0x0010): Could not reconnect to ad.server provider.

auth.log pam_sss(sshd:account): Access denied for user monitor: 4 (System error) sshd[3126935]: fatal: Access denied for user monitor by PAM account configuration [preauth].

Does anyone have any ideas?

Hi,

are there crashes of the sssd_be process? If yes, do you have core-dumps?

bye, Sumit
