I am attempting to setup communication between 2 ldap servers but having issues when trying to limit access. I have dug around the source a bit and found a few commands but unable to find any documentation anywhere on them.

olcDbAclBind

slapd-ldap(5) acl-bind.

olcDbACLAuthcDn olcDBAclPasswd

Both of those are obsolete, kept for compatibility with 2.3. Do not use them.

I've tried multiple options but without some information I am just guessing. Any chance these are documented somewhere and I've just not found it?

Hello.

I'm trying to replicate access rules and limits for one of my databases, but with no success: suse:~ # cat olcAccess-syncrepl.ldif dn: olcDatabase={1}mdb,cn=config changetype: modify add: olcSyncrepl olcSyncrepl: {1}rid=002 provider=ldap://ldap1.local bindmethod=simple binddn="cn=admin,cn=config" credentials="TopSecret" searchbase="olcDatabase={1}**mdb,cn=config" attrs="olcAccess,olcLimits" timeout=3 network-timeout=0 starttls=yes tls_cert="/etc/openldap/ldap.**pem" tls_key="/etc/openldap/ldap.**key" tls_cacert="/etc/ssl/local-ca.**pem" tls_reqcert=demand tls_crlcheck=none

suse:~ # ldapmodify -H ldap://ldap2.local -ZZxWD cn=admin,cn=config -f olcAccess-syncrepl.ldif Enter LDAP Password: modifying entry "olcDatabase={1}mdb,cn=config" ldap_modify: Other (e.g., implementation specific) error (80) additional info: Base DN "olcAccess,olcLimits" is not within the database naming context

slapd-2.4.33 if it matters.

The error message is a bit garbled (obviously the Base DN is wrong) but the error is basically correct. You're trying to replicate the wrong thing from the wrong place. Setting a syncrepl consumer on the olcDatabase={1}mdb database lets you replicate the *content* of that database. To replicate the *configuration* of that database your consumer must be set where that configuration is stored.

The configuration is stored in olcDatabase={0}config.

Thanks Howard, but I still cannot get things working.

Could you exaplain me following (i read documentation but it is not clear enough for me to understand): Does parameter `searchbase' in olcSyncrepl configuration statement set search starting point or it sets just a database name (which is set in olcSuffix) where search is performed?

Here is my configuration provider setup: ldap1:~ # ldapsearch -H ldap://ldap1.local -LLLZZxWD cn=admin,cn=config -b olcOverlay={0}syncprov,olcDatabase={0}config,cn=config '&' dn: olcOverlay={0}syncprov,olcDatabase={0}config,cn=config objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: {0}syncprov olcSpCheckpoint: 100 10 olcSpSessionlog: 100

Here is my configuration consumer: ldap2:~ # ldapsearch -H ldap://ldap2.local -LLLZZxWD cn=admin,cn=config -b olcDatabase={0}config,cn=config '&' olcSyncrepl Enter LDAP Password: dn: olcDatabase={0}config,cn=config olcSyncrepl: {0}rid=001 provider=ldap://ldap1.local bindmethod=simple bind dn="cn=admin,cn=config" credentials="TopSecret" searchbase="cn=con fig" scope=sub filter="(olcDatabase={1}mdb)" attrs="olcAccess,olcLimits" retr y="60 +" timeout=3 network-timeout=0 starttls=yes tls_cert="/etc/openldap/lda p.pem" tls_key="/etc/openldap/ldap.key" tls_cacert="/etc/ssl/local-ca.pem" t ls_reqcert=demand tls_crlcheck=none

A bit offtopic: could you guys implement some kind of human friendly formatting for long line statements and ACLs? So previous statement would look like this when i fetch it from catalog: olcSyncrepl: {0}rid=001 provider=ldap://ldap1.local bindmethod=simple binddn="cn=admin,cn=config" credentials="TopSecret" searchbase="cn=config" scope=sub filter="(olcDatabase={1}mdb)" attrs="olcAccess,olcLimits" retry="60 +" timeout=3 network-timeout=0 starttls=yes tls_cert="/etc/openldap/ldap.pem" tls_key="/etc/openldap/ldap.key" tls_cacert="/etc/ssl/local-ca.pem" t ls_reqcert=demand tls_crlcheck=none
