Login not found
Error on attempt to log in. Username not found in the pool.
Invalid redirect URL
If the yc_sub_hint and yc_login_hint parameters were not specified when attempting to log in, the pool user gets redirected to the address specified in the redirectUrl parameter. The error means that the address in redirectUrl is not valid.
Subject not found
Failure to find the user the login attempt was registered for. Check whether yc_sub_hint and yc_login_hint are correct.
