Hello Derek,

I'm running 2012 R2 AD DCs with native AD rfc2307 schema (never used 
Identity Management for UNIX) and using powershell scripts to create 
user and group accounts and populate following attributes:

to support Samba 4.1.x domain member servers.

Also, all of the above attributes can be set manually using ADUC's 
Attribute Editor by enabling Advanced Features option under View menu item.

Below are relevant entries from  smb.conf:
    workgroup = DOMAINNAME
    security = ADS
    realm = DOMAINNAME.COM
    encrypt passwords = yes
    local master = no
    idmap config *:backend = tdb
    idmap config *:range = 70001-80000
    idmap config DOMAINNAME:backend = ad
    idmap config DOMAINNAME:schema_mode = rfc2307
    idmap config DOMAINNAME:range = 80001-3100000
    winbind nss info = rfc2307
    winbind trusted domains only = no
    winbind use default domain = yes
    winbind enum users  = yes
    winbind enum groups = yes
    winbind expand groups = 3

    passwd:      files winbind
    group:       files winbind

    auth        sufficient    pam_winbind.so use_first_pass
    account     [default=bad success=ok user_unknown=ignore] pam_winbind.so
    password    sufficient    pam_winbind.so use_authtok
    session     required      pam_winbind.so use_first_pass

and appropriate symbolic links:
    libnss_winbind.so -> /usr/local/samba/lib/libnss_winbind.so
    libnss_winbind.so.2 -> /usr/local/samba/lib/libnss_winbind.so.2

    pam_smbpass.so -> /usr/local/samba/lib/security/pam_smbpass.so
    pam_winbind.so -> /usr/local/samba/lib/security/pam_winbind.so
