sometimes when I run dcli command in vCSA 6.7U1 I don't get any results but just an error message like this one:
dcli> com vmware cis tasks list --return-all true +username firstname.lastname@example.org
Unable to authenticate user. Please enter the credentials again.
Server error: com.vmware.vapi.std.errors.Unauthenticated
This method requires authentication.
I use dcli in interactive mode. I checked it with +credstore-add and with +username before, but the result is the same.
