dynamic config replication

[Gerard Ranke <gerard.ranke@hku.nl>]

Hello list,

Openldap 2.4.45 here, on 1 producer and 4 consumers. ( I'll attach
relevant parts of the configuration at the end of this message. )
Following the scripts from test059, I configured the producer to serve
up a cn=config backend for the consumers. This seems to work nicely at
first: When you start a consumer from a minimal config, it loads the
producers schemafiles and the cn=config, and replication of the main
database is fine. Also, when fi. changing the loglevel on the producers
cn=config,cn=slave, the consumers pick up this change in their cn=config.
However, when I modify an olcAccess line on the producers
cn=config,cn=slave database, I get these errors on the consumer:

slapd[26324]: syncrepl_message_to_entry: rid=002 DN:
olcDatabase={1}mdb,cn=config,cn=slave, UUID:
7cff5ef6-90b1-1037-9d95-6dfd3149c2dc

slapd[26324]: syncrepl_entry: rid=002 olcDatabase={1}mdb,cn=config
slapd[26324]: null_callback : error code 0x43

slapd[26324]: syncrepl_entry: rid=002 be_modify failed (67)
slapd[26324]: do_syncrepl: rid=002 rc 67 retrying

>From the error code ox43, it seems that the replication is somehow
trying to change the rdn, olcDatabase{1}mdb, on the consumer, which
makes no sense to me.

>From the producer, cn=config,cn=slave:
( This is identical to the consumer's cn=config )

dn: cn=config,cn=slave

I'll leave the rest PM, except for:

dn: olcDatabase={0}config,cn=config,cn=slave
objectClass: olcDatabaseConfig
objectClass: olcConfig
objectClass: top
olcDatabase: {0}config
olcRootDN: cn=root,cn=config
olcRootPW: xxxxxxxxxxxxxx
olcSyncrepl: {0}rid=002 provider=ldap://xxx.xx.xx bindmethod=simple
binddn="cn=config,cn=slave" credentials="xxxx"
tls_cert="/etc/ssl/certs/xxx.cert" tls_key="/etc/ssl/private/xxx.key"
tls_cacertdir="/etc/ssl/certs" tls_reqcert=demand tls_crlcheck=none
searchbase="cn=config,cn=slave" schemachecking=off
type=refreshAndPersist retry="5 5 10 +" suffixmassage="cn=config"
olcSyncUseSubentry: FALSE

This is identical to the consumers olcDatabase={0}config,cn=config entry.

Hopefully somebody can point me in the right direction!
Many thanks in advance,
