DC user creating issue when enable SDP technician access to DC

DC user creating issue when enable SDP technician access to DC

Hi. I'am testing integration between SDP 9.3 and DC 10.0. Integration was configured using the guide.
When I create technician in SDP and enable access to DC and MDM for him, a user with empty username is created in the DC. Domain name is filled, but User name is grayed out.
This technician can log in to SDP and have access to DC from SDP, but can't log in to DC without SDP.
