   This is a trouble shooting issue from a community user jin xiang:
   
   I created an Iceberg catalog in Gravitino, which uses a HMS as the backend, 
and the HMS cluster enables Kerberos authentication. It seems that, even I have 
provided both the krb5.conf and keytab files, it still failed to connect, and 
reports "SASL negotiation failure" error:

 />
   
   and here is the configuration in Gravitino:
