[Freeipa-users] [pam] [sss_dp_on_reconnect] (0x0010): Could not reconnect to provider.

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?
