Debian 10 x86_64 vanilla, openldap, slappasswd, can't use SSHA512

Hi,

The ldap install is very simple.
I can use slappasswd without options, the password changes and I can use ldapsearch.
But if I use:
Code:slappasswd -h '{SSHA512}' -o module-load=pw-sha2.la -o module-path=/usr/lib/ldapand
Code:#ldapmodify -Y EXTERNAL -H ldapi:///

dn: olcDatabase={0}config,cn=config
changetype: modify
replace: olcRootPW
olcRootPW: the_pass_given_by_slappasswdthe password changes, but the new one gives an
Code:# ldapsearch -x -H ldap://127.0.0.1 -b "dc=example,dc=com" -D cn=admin,cn=config -W
Enter LDAP Password:
