Attribut msDS-KeyCredentialLink is missing

Hello,
I just updated my Samba AD from version 4.23 to 4.24 (many version upgrades=
 before), everything works very well and yet I can't activate WHfB.
While testing, I realize that the attribute msDS-KeyCredentialLink is not p=
resent in my schema (present on my test AD but that I created from Samba 4.=
23).
How can I create this attribute?

# samba-tool domain schemaupgrade --schema=3D2019 -v
No changes applied to schema
#  ldbsearch -H /var/lib/samba/private/sam.ldb -b "cn=3DSchema,cn=3DConfigu=
ration,DC=3D...." -s base objectVersion
dn: CN=3DSchema,CN=3DConfiguration,DC=3D...
objectVersion: 88
# samba-tool domain level show
Domain and forest function level for domain 'DC=3D...'
Forest function level: (Windows) 2016
Domain function level: (Windows) 2016
Lowest function level of a DC: (Windows) 2016

Thanks for help.
