Cause

The sysadmin account is the only account that can register SSO in a Data Domain. 

In this case, you are getting Administrator credentials required errors. Data Domain was discovered in DPC with a user other than sysadmin and that is causing this to fail.

Resolution

In the log, you see the following credential error that is causing registration to fail:

Caused by: com.emc.clp.spi.ForbiddenException: Administrator credentials required for the SSO registration
  • To register with SSO, you have to use the sysadmin account as that is the only account that can register SSO. Even other admin accounts do not have that right. 
  • When Data Domain was discovered in DPC, it may not have been given the sysadmin account. Edit the Data Domain in the DPC system management page and put in the sysadmin account and the password for that account. 
  • Attempt to register SSO again from DPC UI.
Registration should be successful.
