You should probably pose that question to the 389ds team.

*strongly* discourage users from distributing hashes around and
recommend hashes are not made available. Rather users should use
kerberos, or as a less desirable alternative LDAP simple binds to
authenticate. Brute forcing weak passwords even w/o random tables is
easy these days with the available on-demand computing power provided by
cloud operators, so distributing hashes is riskier than ever, especially
old hashes based on DES or MD5, but SHA-1 is not far down the list.
