samba - Apr 2022 - set a secondary password for all users under SAMBA

In order toenable SSO with Guacamole, we would like to create a secondary same
password(256 characters long) for each user under SAMBA.

Thispassword would then be used in the background to establish (after
successfullogin via OIDC to Guacamole) around the RDP connection.


Is thissomehow possible? Or is it possible to use a replication of the SAMBA
servers(currently 2 -> 4), where this password is valid for every user?
