SQL Server 2000: "Login failed linked server windows authentication for user "(null)". Reason: Not associated with a trusted SQL Server connection". The errors listed above is nt authority anonymous logon sql server 2012 very typical when deploy linked server with delegation. They actually are thrown by the linked server and pass by middle server to the client application. In this post, I will linked server error 18456 login failed for user discuss how to properly configure SQL instances and Windows environment in most common scenario and try to make configuration steps as explicit as possible. By using delegation in distributed query, such as linked server query, the SQL instance obtains impersonated token of the user logon credential to gain access to resources of another SQL instance, the linkedSpn Registered
server. In delegation setting, the client connection and linked server object are configured to use integrated authentication in SQL Server’s term as opposed to SQL login. Some time integrated authentication also referred as trusted connection or Windows authentication. Linked server login can also use SQL login, but it is not discussed here.
To simplify the discussion, let’s assume two SQL Server instances are installed on machine A and B respectively. Also, let’s assume A is the middle server that has a linked server object configured which points to a SQL instance on machine B. If the client is on machine C different from A, we call it double-hop setting; if the client is collocated with middle server machine A, we call it single-hop setting. In single-hop setting, it is relatively straightforward to configure linked server to work. Believe or not, double-hop setting requires more careful configurations as you will see. This is because in single-hop setting, windows NTLM authentication, which is available in most common setting if all machines are windows, is sufficient for delegatiolog in tour help Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow the

The default mapping states that SQL Server uses the user credentials of the local login when connecting to the linked server on behalf of the login. This is equivalent to executing sp_addlinkedsrvlogin with @useself set to true for the linked server, without specifying a local user name.

This is caused when SQL Server tries to "pass through" the NT login token to the remote server. It doesn't have permission to pass the token through. The remote server looks for this because the local servers connects with Integrated Security. You need "Security Account Delegation" to be configured for the local server. As for the default mapping... What MSDN says is that if you have "MyDomain\bob" locally then you have an "virtual" entry "stored" locally called "MyDomain\bob". There is no reconciliation of the 2 servers be

In SQL Server 2005 they have added a whole load of security issues that make this harder than it should be. The words "Kerberos Authentication" will become the bain of most sys-admins/DBA's lives. It effectively is used for pass-through authentication. Here are the basics of what you need. 1) The servers (A and B) need to be set-up in Active Directory(AD) with delegation for Kerberos enabled. (this is set through your active directory admin panel) 2) The service account that your SQL Servers run under need to have de
