Thank you Michael for the link.
It probably what im running into.
If i understand correctly, the lastbind functionality has been integrated into the main slapd binary. If yes, what do I need to do in order to use it?

Im looking at this:

I decided to simply continue building the cn=config and noticed the new olcLastBindPrecision attributes under several DNs.

dn: cn=schema,cn=config
olcAttributeTypes: ( OLcfgDbAt:0.22 NAME 'olcLastBind' EQUALITY booleanMatch SYNTAX OMsBoolean SINGLE-VALUE )
olcAttributeTypes: ( OLcfgDbAt:0.23 NAME 'olcLastBindPrecision' EQUALITY integerMatch SYNTAX OMsInteger SINGLE-VALUE )
olcObjectClasses: ( OLcfgGlOc:4 NAME 'olcDatabaseConfig' DESC 'OpenLDAP Database-specific options' SUP olcConfig STRUCTURAL MUST olcDatabase MAY ( olcDisabled $ olcHidden $ olcSuffix $ olcSubordinate $ olcAccess $ olcAddContentAcl $ olcLastMod $ olcLastBind $ olcLastBindPrecision $ olcLimits $ olcMaxDerefDepth $ olcPlugin $ olcReadOnly $ olcReplica $ olcReplicaArgsFile $ olcReplicaPidFile $ olcReplicationInterval $ olcReplogFile $ olcRequires $ olcRestrict $ olcRootDN $ olcRootPW $ olcSchemaDN $ olcSecurity $ olcSizeLimit $ olcSyncUseSubentry $ olcSyncrepl $ olcTimeLimit $ olcUpdateDN $ olcUpdateRef $ olcMultiProvider $ olcMonitoring $ olcExtraAttrs ) )

dn: olcDatabase={-1}frontend,cn=config
olcLastBind: TRUE
olcLastBindPrecision: 0

dn: olcDatabase={0}config,cn=config
olcLastBind: TRUE
olcLastBindPrecision: 0

dn: olcDatabase={1}mdb,cn=config
olcLastBind: TRUE
olcLastBindPrecision: 0

dn: olcDatabase={2}monitor,cn=config
olcLastBind: TRUE
olcLastBindPrecision: 0

I tried to import my data.ldif but get this error:

slapadd -n 1 -F /opt/symas/etc/openldap/slapd.d -l data.ldif
<= str2entry: str2ad(authTimestamp): attribute type undefined
slapadd: could not parse entry (line=24)
Closing DB...

I'm probably missing a configuration... in my cn=config...

Any input is appreciated!

Thank you,

Maybe you're hitting this one:

Ciao, Michael.
