i found out that as long as DDS overlay is active on the mdb database,
startup failed. if remove DDS everything is fine again.

that’s the DDS config:
dn: olcOverlay={1}dds,olcDatabase={1}mdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcDDSConfig
olcOverlay: {1}dds
olcDDSdefaultTtl: 7d

looks like a bug?

Subject: startup failed

Hi,

I set up an openldap server with all desired configs (cn=config, mmr, etc etc) as node 1.
Then I start it up, which is quite slow (I think it waits on node 2 which is not available yet).
Then I add an empty base tree:

dn: dc=example,dc=net
objectClass: dcObject
objectClass: organization
o: ORG1
o: ORG2
dc: example

dn: cn=admin,dc=example,dc=net
objectClass: organizationalRole
cn: LDAP Admin
cn: admin

dn: o=org1,dc=example,dc=net
o: ORG1
objectClass: organization
objectClass: top

dn: o=org2,dc=example,dc=net
o: ORG2
objectClass: organization
objectClass: top

After that restarting slapd always fails. That’s in debug log:

Does anybody see the problem?
