Hi Everyone,

I have created Custom User Storage Provider to Bridge my legacy application and Keycloak. I have users in my legacy DB with passwords. They are able to log in using keycloak. Now, I have updated the password in Keycloak for the federated user as we are moving the whole IAM to Keycloak. After updating the password in Keycloak, I am not able to log in.

Can anybody help with what approach needs to be taken in this situation?

Hi Zak, These ones `UserStorageProvider`, `UserLookupProvider`, `CredentialInputValidator`,`UserQueryProvider`

To be able to update the password, I think you need to implement this one as well `CredentialInputUpdater`
