After setting UPN same as SPN, I did undo the SAS_SERVICE_PRINICIPAL setting on the level_env_usermods.sh file. So the compute tier does not have a keytab of it's own. I just copied the meta keytab on the compute (not knowing if it's needed or not). So should the keytab contain the SPN of both meta and compute ?
SAS/sastestmd.healthcore.local --meta
SAS/sastest.healthcore.local -- compute.
Set the UPN = SAS/sastestmd.healthcore.local and add the SAS_SERVICE_PRINICIPAL= SAS/sastestmd.healthcore.local on the level_env_usermods.sh file since UPN will not be equal to SPN for compute.
