OpenLDAP Tuning Keys

Starting with ZCS 6.0, the configuration is stored in a database. This allows the ability to make changes to the OpenLDAP configuration on the fly. To support this, a number of keys were added to Localconfig. When modified via zmlocalconfig, the values will automatically be updated in the OpenLDAP server configuration within 2 minutes.

OpenLDAP Common keys

  • Set the threads count to an appropriate level. The ZCS default is 8, which is fine for 1 or 2 CPU servers. The general rule of thumb is 4 threads for every real core.
zmlocalconfig -e ldap_common_threads=8
  • Set the toolthreads count to an appropriate level. The ZCS default is 1. It should be set to the number of real cores you have available. The purpose of the toolthreads setting is to decrease the amount of time it takes to slapadd a database.
zmlocalconfig -e ldap_common_toolthreads=4

ldap_common_loglevel = 49152 ldap_common_require_tls = 0 ldap_common_threads = 8 ldap_common_toolthreads = 1 ldap_common_writetimeout = 0

OpenLDAP Database keys

  • Change the entry cachesize for the primary database. The number set should be the number of configured active accounts and the number of configured active domains. The default is 10000.
zmlocalconfig -e ldap_db_cachesize=50000
  • Set idlcachesize for the primary database. The number set should be the same as the cachesize setting.
zmlocalconfig -e ldap_db_idlcachesize=50000
  • Change the dn entry cachseize for the primary database. It is highly recommended to leave it at the default value of zero, which means an unlimited DN cache. If it is set to a non-zero value, it should be no less than two times the entry cache.
zmlocalconfig -e ldap_db_dncachesize=0


ldap_db_cachefree = 1 ldap_db_cachesize = 10000 ldap_db_checkpoint = 64 5 ldap_db_dncachesize = 0 ldap_db_idlcachesize = 10000 ldap_db_shmkey = 0


OpenLDAP Accesslog Database Keys

ldap_accesslog_cachefree = 1 ldap_accesslog_cachesize = 10000 ldap_accesslog_checkpoint = 64 5 ldap_accesslog_dncachesize = 0 ldap_accesslog_idlcachesize = 10000 ldap_accesslog_shmkey = 0
