IHAC who is setting up Powerscale 9.4 with KDC running on RHEL 8.6 and experienced errors when trying to create SPN by using the command below

isi auth krb5 spn create –provider-name=VLAB.LOCAL –spn=hdfs/isilonzone-cdh2.vlab.local –user=cloudera-scm/admin@VLAB.LOCAL

• Bad encryption type

The situation does not happen with a RHEL 7 or 8.2 KDC though.  If anyone has any ideas on why this is happening, please share your thoughts.
