PowerFlex 4.8: How to Enable Stringent Certificate Feature

Summary: Many users have CA policies that prohibit IP addresses in the Certificate Subject Alternative Name (SAN) and only Fully Qualified Domain Names (FQDNs) are allowed. The lack of IP addresses in the certificate conflicts with PowerFlex Manager logic when it comes to the zipper or yum repositories that we use. PowerFlex 4.8 has a new feature to support stringent rules for certificates. This is a new security mode within package manager. Now, when creating a custom certificate or the Powerflex appliance certificate, the customer can choose between Standard and Stringent modes.

  1. Add the DNS Hostname details:

 

Note: It is always recommended to include one DNS per entry; however, if this is not possible, the Management DNS can be used for the Data entries as well. If there are physically isolated OOB networks, a DNS entry on the OOB network is required to resolve the FQDN to the OOB ingress IP.

 

Note: Once the CSR is generated, do not deviate from what is in the Subject Alternative Name (SAN) Section; otherwise, the system shows an error when trying to upload the signed certificate in the Upload SSL certificate section.
