Troubleshooting Steps

• Confirm that the SingleStore user on the node(s) in question can access the path defined for gssapi_keytab_path in the memsql.cnf file.
• Confirm that gssapi_keytab_path is defined in the memsql.cnf file for only the aggregator nodes in the cluster.
• For more information on configuring Kerberos authentication, follow the Copying the Keytab File to SingleStore DB documentation.
