It's nearly impossible to find a good documentation on how to setup pcache overlay via cn=config. As i said with slapd.conf everyting works. Any hint that get things working as expected? When I'm starting the slapd the log is showing: ----------- mdb_db_open: database "dc=example1,dc=net": dbenv_open(/var/symas/pcache). ----------- Same Server different problem I did not add memberof, because everytime I add the overlay with the following LDIF (should be replaced by dynlist in the near future) But I think it should work: -------------- dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: memberof.la dn: olcOverlay={1}memberof,olcDatabase={2}ldap,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcMemberOfConfig olcOverlay: {1}memberof olcMemberOfGroupOC: groupOfNames olcMemberOfMemberAD: member -------------- The slapd chrashes and "slapcat -n0" is giving e the following error: --------------- root@ldap-proxy01:~/server-setup/proxy# slapcat -n0 olcAttributeTypes: value #741 olcAttributeTypes: Duplicate attributeType: " z*V" config error processing cn={4}msuser,cn=schema,cn=config: olcAttributeTypes: Duplicate attributeType: " z*V" slapcat: bad configuration file! ---------------
