[keycloak-user] Passwords with umlauts

Hi, I have a problem with user passwords which contain umlauts (like Ö Ä Ü, common ones in germany). They will be stored, but when i try to get a token, it always fails with "Invalid user credentials". I read https://www.keycloak.org/docs/3.4/server_installation/index.html#unicode-... on how to enable unicode in the DB, but i don't get which columns to alter. Since the password will be stored hashed and salted, will altering the DB have any effect at all? Technical setup: Keycloak 3.4.3.Final with an Oracle DB Regards zitrone
