We are porting a Windows Phone 8.1 app to UWP. In the original app we used PasswordVault (Windows.Security.Credentials) to store user credentials and everything just worked fine. After the porting every operation related to PasswordVault throws exception with the following message:
The requested operation cannot be completed. The computer must be trusted for delegation and the current user account must be configured to allow delegation. Failed to open store.
If I run the app on my local machine everything is ok, but on the office tablets (with a lot of additional security things like bitlocker, user domains, etc.) the error just shows up.
I also tried to create a blank app, and add/retrieve credentials to/from PasswordVault, but the same happened.
Any ideas?
