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**

Empieza reproduciendo la conexión Kerberos con un realm no predeterminado, comparando mssql-cli con el comportamiento funcional de sqlcmd y la configuración default_realm de /etc/krb5.conf. Traza dónde se selecciona el destino de autenticación de SQL Server; se considera terminado cuando mssql-cli se autentica correctamente cuando el servidor utiliza un realm distinto del predeterminado y el error GSSAPI indicado deja de producirse.
