File Server authentication with domain credential

[timmer]

Hi, all!
I'm not very good in mastering Alfresco so i have a problem:
I had working Alfresco (on Ubuntu 12.04) integrated with Active Directory (Windows Server 2008 R2). Also users had mapped drive "Alfresco". I installed new domain controller (Windows Server 2012 R2) and retired the old one. Since I've done it mapped drive is not mapping anymore. I replaced 'ldap.authentication.java.naming.provider.url' option in alfresco-global.properties with new server's ip-address.
I can access Alfresco via web with domain credential, I can access file share via FTP with domain credential, but when i try to map it as a network share I get login/password request and it doesn't accept my domain credential.
Can't find any troubleshooting article neither in Wiki nor on forum nor in Google
Please, help!

P.S. Sorry for my english, it's not my native language.

This potentially could be the problem. I'm not for sure.

There was no Identity Manager for NIS installed in old server.
Found logs in Alfresco:

So as i understand problems in kerberos, but can someone tell me how to resolve it? It worked fine with old server…
May be I must update Alfresco to the latest version to make it work with WinServer2012R2 or smth like this?
Still need help.
