Part of the difficulty comes when you only want to see certain LDAP groups, or permit access only for certain groups. When those groups are scattered around a poorly organized LDAP layout, it means you need to cache *all* the relevant OU's. Unless your pipeline to your remote environment is large, or you have deployed local LDAP servers to provide a remote mirror, the bulk pre-caching times out and causes all sssd related daemons to turn off after working for a short period, the daemons die. This was *nasty* when I observed it a few years ago, I had to convince the LDAP admins to set up new mirror groups in a much smaller OU workspace. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
