Has this changed?
This has not changed. SSSD does not have support for some nss_files-type maps at all, like networks or hosts, meaning that even if you had those objects stored in LDAP, SSSD wouldn't even be able to resolve them (although some friendly Suse developers are adding support for more maps). But even when this is implemented, then the request still has to go from the client application over a socket to the deamon and back. We'd still be missing the fast in-memory cache support like we do have for passwd,group and initgroups.

Are you asking if winbind has support for some sort of nss_files caching or the other way around if sssd can wrap wibind using its cache? btw I've seen people using nscd mostly with maps that sssd does not support at all, together with nslcd (nss-pam-ldap) _______________________________________________ sssd-devel mailing list -- sssd-devel@lists.fedorahosted.org To unsubscribe send an email to sssd-devel-le...@lists.fedorahosted.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.fedorahosted.org/archives/list/sssd-devel@lists.fedorahosted.org
