How to properly configure domain user authorization in Linux MINT?

Question

linux

Good afternoon, for the third day this question has been tormenting, it is
necessary to enter a workstation with Linux MINT 17.2 OS into the domain , the
domain controller is Windows server 2008 R2 standart
, Linux enters the domain normally, all tests pass with a bang,
Kerberos5 + Samba + Winbind is used
, there are 2 problems :
1. During authorization, the list of domain users is not loaded, more precisely, it is loaded but not always
2. When you try to authorize under the login of a domain user, the system first swears at the access rights to the $HOME/.dmrc file, then gives an error: The system administrator has blocked your account (Even though it's not)...

Answer 1

As if everything is already written and fit

Answer 2

That's how everything is set up and working...
I can't access the system desktop as a domain user
