I'm trying to set up slapo-pcache using cn=config, and this is my settings: dn: olcDatabase={1}ldap,cn=config objectClass: olcConfig objectClass: olcDatabaseConfig objectClass: olcLDAPConfig objectClass: top olcDatabase: {1}ldap olcRootDN: cn=admin,cn=config olcAccess: {0}to * by * read olcDbACLBind: bindmethod=simple binddn="ou=group,dc=remote" credentials="password" tls_cacert="/etc/ssl/certs/ca-certificates.crt" starttls=yes olcDbURI: ldap://remote.host olcSuffix: dc=remote dn: olcOverlay={0}pcache,olcDatabase={1}ldap,cn=config objectClass: olcPcacheConfig objectClass: olcOverlayConfig objectClass: olcConfig objectClass: top olcOverlay: {0}pcache olcPcache: hdb 10000 1 50 100 olcPcacheAttrset: 0 member olcPcacheTemplate: "(objectClass=)" 0 3600 dn: olcDatabase={0}hdb,olcOverlay={0}pcache,olcDatabase={1}ldap,cn=config objectClass: olcPcacheDatabase objectClass: olcHdbConfig objectClass: olcDatabaseConfig objectClass: olcConfig objectClass: top olcDatabase: {0}hdb olcDbDirectory: /var/lib/ldap/cache olcDbIndex: objectClass eq olcDbIndex: pcacheQueryid eq But each time I'm trying to run ldapsearch -b"cn=test2,ou=group,dc=remote" '(objectClass=*)' member I'm getting QUERY NOT ANSWERABLE/QUERY NOT CACHEABLE errors in the log. Besides, it is impossible to modify attributes olcPcacheTemplate/olcPcacheAttrset: modify/add: olcPcacheTemplate: no equality matching rule Can anyone confirm that the one have managed to make slapo pcache working on 2.4.31?
