LMTP said: 550-Mailbox unknown or you do not have authorization to see it

I am building a new mail server to replace an older EL6 server. The new
server is Centos 8. I keep getting this response when trying to deliver
email to a local account stored in LDAP.

host mail.example.org[/var/lib/imap/socket/lmtp] said:
550-Mailbox unknown.  Either there is no mailbox associated with this
550-name or you do not have authorization to see it.
550 5.1.1 User unknown (in reply to RCPT TO command))

I have tried replacing the new configs with my old working configs from the
EL6 server but they get the same result.

a postmap -q against the LDAP table config returns the appropriate
information. I am wondering if the key is the 'or you do not have
authorization to see it` part of the message. What exactly does LMTP need
to authorize the delivery?

Enabling verbose logging on LMTP and LDAP did not give any clues.

Any assistance is appreciated. I have been googling and hitting my head on
the desk for days.

Thanks,
