[keycloak-user] Passwords with umlauts

[zitrone at gmx-topmail.de]

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-considerations-for-databases 
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
