So nsslapd-errorlog-level doesn't have it. https://access.redhat.com/documentation/en-US/Red_Hat_Directory_Server/10/html-single/Administration_Guide/index.html#configuring-log-levels There is line in the docs under nsslapd-errorlog-level attribute description: 131072 — Microsecond resolution for timestamps instead of the default seconds. It has to be removed.
The update is now available on the Customer Portal.
