[keycloak-user] Passwords with umlauts

[Andreas Lau]

Hi,
Not quite sure how to solve this in first place. But as long nobody has a real answer to this. Have you considered to disallow umlauts for password via the password policy?
You possibly could define a regexp using the password policy type "Regular Expression" that disallow such umlauts. I know it's not the answer of your question, but may be a workaround until someone can give you a more sophisticated answer.

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
