Hi, we have openLDAP

# /usr/sbin/slapd -V
@(#) $OpenLDAP: slapd 2.4.44 (Aug  2 2017 17:18:28) $
        mockbuild@x86-ol7-builder-01.us.oracle.com:/builddir/build/BUILD/openldap-2.4.44/openldap-2.4.44/servers/slapd

in two Oracle Linux servers configured as multi-master servers.

By default we know that SSHA is used as the hash algorithm.
We want to change that to M5 or SHA in order to hash the user passwords now and then.

We use OLC (cn=config).

How can set the default hash algorithm to MD5 o SHA?

Thanks in advance.
