How to suppress Edge credential DLO 8.0

I believe, when the DLO client is outside the domain and when it is launched, it requests for the domain credentials for access to the Network User Data Folder (This is independent of the EDGE server feature).

If the DLO client doesn't have access to the NUDF or if Backup Over Internet feature isn't enabled, then backups to the Local User Data Folder should run, however there isn't any way to suppress the credentials prompt.

Welll its not entirely like I see it:

When the PC starts up at home and connects to my wifi, DLO asks for credentials to Internet backup, pls. see attached.
Backup to local user folder is disabled - we do only backup to a network folder

Is the option "Enable BOI" checked in the Profile settings ?

No its un-checked, pls. see attached.

If the DUDF is enabled, do you still receive the credential prompt ?
 

No DUDF is not enabled.
And if i do enable and ie. point to c:\windows\temp.
uninstall the app on the PC, delete my profile on the server and then reinstall the agent on the PC... I still get the credential prompt for Backup over Internet....

I followed this article: https://support.symantec.com/en_US/article.TECH49221.html

Just checked internally and this seems to be expected behavior for the first launch.

On the first launch client will not know whether BOI is enabled or not. It 
tries to go to BOI mode to get the BOI status from DB. So credentials wil be 
asked.
