We joined a samba 4.11 DC (sernet-packages) into a windows domain  with
round about 170.000 objects. After "commiting SAM database" has finished
after 21 hours we now have a database-file but if we try to list the
content with "ldbsearch --url=/var/lib/samba/privat/sam.ldb" we get the
following error:

ldbsearch --url=/var/lib/samba/private/sam.ldb
Unable to determine the DomainSID, can not enforce uniqueness constraint
on local domainSIDs

dsdb_schema_from_db() failed: 32:No such object: dsdb_schema: failed to
search attributeSchema and classSchema objects: No such Base DN:

All the DNS-databases are empty

dc1:/var/lib/samba/private#  ldbsearch
# returned 0 records
# 0 entries
# 0 referrals


Any hint what went wrong?
