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. https://www.keycloak.org/docs/3.2/server_admin/topics/authentication/pass...

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 ________________________________ keycloak-user mailing list keycloak-user(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/keycloak-user
