Good!
So I would  clean the directory /etc/ovirt-engine/aaa from the profile1.properties, profile1-authn.properties, profile1-authz.properties files  and the same for profile2 
and perhaps also inside /etc/ovirt-engine/extensions.d/ there should be some xxx-authn.properties (perhaps xxx= ldap.com, the profile name you chose in previous attempts) remove them too
and restart ovirt-engine service or the server itself (eventually putting into global maintenance if Self Hosted Engine setup)
Then I would rerun the interactive setup

ovirt-engine-extension-aaa-ldap-setup

select 9 - OpenLDAP Standard Schema
select to use DNS and policy 1 (single server) that should be resolved as you pointed out and put ldap.lab.local
select Insecure
select search user uid=node1,ou=People,dc=lab,dc=local
enter the password
enter the base dn  ou=People,dc=lab,dc=local
decide if you want sso for vms yes/no
specify profile name lab.local
