DD is Refusing the Single Sign-On Connection to DPC, Issue Must be Checked from DD

From DDOS 6.2.0.20 and later, DDOS added Single Sign-On (SSO) authentication for Data Protection Central (DPC). This SSO allows access to the PowerProtect DD System Manager UI from DPC without using DD credentials.

The DPC Data Domain integration requires registration of the Data Domain at the DPC console. This may fail with the error "Failed to get SSO auth endpoints" reported at Data Domain sms.info debug logs under /ddr/var/log/debug/sm directory.

Ensure that the DPC FQDN and DPC hostname are properly resolved by the Data Domain either by DNS or local host resolution. These can be added to the list of known Data Domain hosts.

• At DD CLI, add the DPC FQDN IP address, DPC Hostname, and DPC FQDN to the list of known Data Domain hosts using the following command:

# net hosts add {<ipaddr> | <ipv6addr>} <host-list>
                                       Add a host list entry
