GSSAPI operation failed with error - An invalid status code was supplied (Server not found in Kerberos database).

mssql-cli try only default_realm in /etc/krb5.conf
if mssql has another realm than default it will throw exception.

**# sqlcmd work normal**

Inizia riproducendo la connessione Kerberos con un realm non predefinito, confrontando mssql-cli con il comportamento funzionante di sqlcmd e con l'impostazione default_realm in /etc/krb5.conf. Traccia il punto in cui viene selezionata la destinazione di autenticazione di SQL Server; il lavoro è completato quando mssql-cli esegue correttamente l'autenticazione se il server utilizza un realm diverso da quello predefinito e l'errore GSSAPI segnalato non si verifica più.
