To resolve this issue an upgrade to DPC 19.7.0-9 or above is required.
For IDPA system, upgrade to IDPA 2.7.6 or above.
If you run into DD SSO issues after upgrading, please open an SR with Dell Support to resolve that issue.
If you do not know the DPC lockbox password, the Lockbox can be removed and rebuilt. This looses all username and passwords in DPC, so they will all have to be reentered.
The procedure to do this is in the DPC Administration Guide, in the Troubleshooting chapter under "Remove the lockbox" and then "create the lockbox" sections.
