Automatic user login to 1C stopped working, how to fix it?

Question

System administration

Actually, I got such a tupnyak.
In the configurator, there were users whose authorization is through "OS authentication" It is
not clear why this all stopped working and people can only log in with a password.
I did not do any manipulations with the domain and 1C.
I tried to restart the 1C and MSQL services, but it did not give any results.
Maybe someone had such a problem, I will be very grateful.
