SQL Server 2012 Management Studio and samba 4

Question

I am experiencing a very weird situation. When logged into my database server with a domain account (which is also a member of the local administrators group) the sa user is unable to connect to SQL Server Management Studio. However, logging in as a local admin account the sa user logs in successfully.

To make things more confusing... when logged into the Windows Server with a domain account (which is also a member of the local administrators group) SQL Server Management Studio will connect using Windows authentication.

A few notes:

1. While logged into the server with a domain account sa CAN connect via sqlcmd .

2. sa can connect via ODBC from other workstations on the domain (logged in as a domain user)

3. The SQL Server authentication is set for SQL Server and Windows authentication mode

4. The sa user does NOT have "Enforce password policy" checked

5. I have tried creating a new SQL admin user with the sysadmin role (same issue)

6. The SQL Server machine is a member of the samba4 domain

My environment:

Database Server

• SQL Server 2012 x64 Standard edition with service pack 3

• Windows Server 2012 R2 Standard x64

Directory Server

• CentOS 6.7 x64

• Samba 4.3

smb.conf

[global]

    workgroup = XYZ
    realm = XYZ.COM
    netbios name = DS01
    server role = active directory domain controller
    dns forwarder = 8.8.8.8
    tls enabled  = yes
    tls keyfile  = tls/key.pem
    tls certfile = tls/cert.pem
    tls cafile   = tls/ca.pem
[netlogon]
    path = /usr/local/samba/var/locks/sysvol/xyz.com/scripts
    read only = No
[sysvol]
    path = /usr/local/samba/var/locks/sysvol
    read only = No
[home]
    path = /home/
    comment = Home Directories
#   read only = No
    browseable = no
    writable = yes
    create mask = 0600
    directory mask = 0700

Answer 1

As I mentioned in my comment. Although there seems to be no answer at this point other than wait for a fix. The workaround is to login as a local user and run SQL Server Management Studio
