Hi all,

Same subject, but with a minor change :) For now, as I explain in a previous mail, it seems we have a working N-Way multimaster replication, still with some problems.

we use RE24, checked out 2 days ago.

But, even if cn=config seems to be correclty replicated, there is a problem with gluing database declarations.

We have a primary provider. Its config backend has been initialized by this command : slapd -f slapd.conf -F slapd.d. All work fine, no errors. The configuration has multiple backends (8), and some are glued.

In the slapd.conf we have something like the following :

database ldap suffix dc=example,o=test subordinate database bdb suffix o=test glue

So, in cn=config, we have :

olcDatabase={2}ldap,cn=config olcSuffix dc=example,o=test olcSubordinate TRUE olcDatabase={3}bdb,cn=config olcSuffix o=test olcOverlay={0}glue,olcDatabase={4}bdb,cn=config olcOverlay {0}glue

Fine. But when the new provider replicates the entire cn=config of the primary provider, it can not replicate this kind of configuration :

Is it a bug ?

I have an idea : reorder declarations into the cn=config to have something like that :

olcDatabase={2}bdb,cn=config olcSuffix o=test olcOverlay={0}glue,olcDatabase={2}bdb,cn=config olcOverlay {0}glue olcDatabase={3}ldap,cn=config olcSuffix dc=example,o=test olcSubordinate TRUE

I have the first olcDatabase={2}bdb,cn=config replicated successfully. But an other problem appears : the DN of olcOverlay={0}glue,olcDatabase={4}bdb,cn=config is not correclty renamed, because of a inexcepted "charset" ? I can reproduce this problem for all types of database. OpenLDAP complains itself and replication does not work. Hum... but I realized that even this "tips" works, OpenLDAP could not be restarted correctly anymore because of the configuration's test...

Any hints, or advice would be most appreciated.
