RHEL 8 OpenLDAP 2.6.4

Trying to use OpenLDAP as a proxy to AD and most of my configuration seems to be working as expected, but when I try to use the rwm-suffixmassage option an LDAP search against the server returns the following error:

No such object (32)

If I remove the rwm-suffixmassage option then I am returned the expected entry.

Relevant config snippet: suffix "dc=subdomain,dc=domain,dc=tld" uri "ldaps://dc1.subdomain.domain.tld/ ldaps://dc2.subdomain.domain.tld/"

chase-referrals no

idassert-bind bindmethod=simple binddn="cn=user,ou=OU,dc=subdomain,dc=domain,dc=tld" credentials="secret" mode=self tls_reqcert=demand tls_cacert=cert.file flags=non-prescriptive

overlay rwm rwm-suffixmassage "dc=subdomain,dc=domain,dc=tld" "dc=domain,dc=tld"

Any help would be appreciated.

Thank you,

SS
