[keycloak-user] Is it possible to update a Password using SAML

Hi all Maybe it's a stupid question and that's maybe the reason I couldn't find an answer for it on the internet. But is it possible, that a service provider (in my case Nextcloud) uses the SAML protocol to update the current users password on the IdP (keycloak)? If yes, does Keycloak support that? thanks a lot for the information Michael Meier
