Hi!

While setting up an OpenLDAP-2.5-based MMR configuration I had set up the master node, then dumped the config database, copied the LDIF to the other node.

However when starting slapd, it failed with the message

slapd[2734]: config error processing olcDatabase={0}config,cn=config: <olcMultiProvider> database is not a shadow

See also https://stackoverflow.com/q/6792212/6607497

The context of olcMultiProvider is:

dn: olcDatabase={0}config,cn=config

objectClass: olcDatabaseConfig

olcDatabase: {0}config

…

olcMultiProvider: TRUE

On the first node I had updated the config using this LDIF:

dn: olcDatabase=${db},cn=config

changetype: modify

delete: olcMirrorMode

olcMirrorMode: TRUE

-

add: olcMultiProvider

olcMultiProvider: TRUE

So I don’t understand why this won’t work on the second node. Specifically I can restart the first node without an issue.

The only difference is that the primary node has a patch against crashing on an invalid olcAuthzRegexp (I had reported).

Well can anybody explain what this message means?

Update: Reading https://www.openldap.com/lists/openldap-technical/201807/msg00051.html (“Do you have a unique olcServerID set in cn=config for both masters”)I realized that I forgot to specify “-S SID” for slapadd. Unfortunately even after using option -S, the error message remains the same.

Kind regards,
