i am trying to setup the pcache overlay to cache routinely used entries in the DIT.  using the below, i am able to load the pcache module:<br><br>ldapmodify -QY EXTERNAL -H ldapi:///<br>dn: cn=module,cn=config<br>changetype:add<br>
objectClass: olcModuleList<br>cn: module<br>olcModulePath: /usr/lib64/openldap<br>olcModuleLoad: <a href="http://pcache.la">pcache.la</a><br><br>then i try to add some caching directives, using the below:<br><br>ldapmodify -QY EXTERNAL -H ldapi:///<br>
dn: olcOverlay={0}pcache,olcDatabase={2}hdb,cn=config<br>changetype: add<br>objectClass: olcOverlayConfig<br>objectClass: olcPcacheConfig<br>objectClass: olcPcacheDatabase<br>olcOverlay: {0}pcache<br>olcPcache: hdb 100000 50 1000 100<br>

olcPcacheTemplate: &quot;(&amp;(objectClass=)(|(memberUid=)(uniqueMember=)))&quot; 3 3600<br><br>i no longer have logs around the failure, but the error message indicated that the olcDbDirectory could not be found.  the DN dn: olcDatabase={2}hdb,cn=config has that specified (olcDbDirectory: /var/lib/ldap), but i am missing something about pcache and the backend sharing this directive.  can anyone point me in the right direction about how to get the pcache overlay setup correctly?<br>
