I have added a novell ldap user federation. When I try to login I get an error page displaying:

Unexpected error when handling authentication request to identity provider.

In the server log it shows a WARN message with “error=invalid_user_credentials”

If I try to login with an incorrect user the message contains “error=user_not_found”, so the user must have been found.

It seems that some unexpectec error occurs while verifying the password. I’m sure it is correct. And I’m assuming that I would not get an unexpected error page if the password is just incorrect.

Any help would be appreciated.
