On the other hand, this is strange:

cn=config

• cn= schema
  • cn={0}core
• olcDatabase={-1}frontend
• olcDatabase={0}config
• olcDatabase={-1}ndb_pl
  • olcoverlay={0}ndbover

Two different databases should not have the same number. ndb_pl should get {1}.

Ignore that cn=config tree. The submitter tells me it was a copy&paste error when he posted the ITS.
