RSA Authentication Manager 8.1 is unable to connect to a Windows shared folder when attempting to create a backup.

The following error appears in the System Log report: : com.rsa.ims.operationsconsole.admin.taskmgr.TaskExecutionException:
Failed to validate the remote backup location

This error occurs when the username format for the Windows shared folder credentials is incorrect.

When configuring a backup in the Operations Console under:
Backup Location → Windows Shared Folder

Make sure that the Folder User Name is entered in this format:

Domain\User

The backup will fail if you enter only the username by itself (for example user) or if you enter a local machine account (for example MACHINE\Administrator or MACHINE\localadmin).

If you enter the username in Domain\User format, Authentication Manager will validate the Windows shared folder successfully and allow the backup to complete.
