ActiveDirectory connector custom error messages

The 'resolveBindException' function in the Active Directory function never gets called when a password is expired. I made a test change by renaming it 'resolveBindError' (taken from standard LDAP connector class) and changing the signature, and now the code gets called but the error messages aren't defined which cause an error when a password is expired:

SimpleSAML\Error\Exception: Key "RESETPASSWORD" for sequence/mapping with keys "ACSPARAMS...." does not exist in core:loginuserpass.twig

I have tried defining custom errors using the getCustomTitles() and getCustomDescriptions() methods but I'm not doing it right, but now I'm wondering if I'm going down the correct path. Any suggestions?

Confronta la funzione resolveBindException del connettore Active Directory con il comportamento di resolveBindError del connettore LDAP standard, inclusi i metodi getCustomTitles() e getCustomDescriptions(). Traccia il percorso degli errori relativi alle password scadute fino a core:loginuserpass.twig e verifica che le chiavi e i messaggi di errore risultanti siano definiti, in modo che la chiave RESETPASSWORD mancante non causi più un’eccezione.
