sql server - Windows authentication trusted connection not working

Question

MSSQL Server is in the "abc" domain and have mixed mode authentication. I am connecting from the machine which is not in domain or in a domain "xyz" but with in the same network using MSSQL Jdbc driver 2.0. I have logged in as admin or account in xyz domain.

It works fine using following url for connection for "sa" or SQL Mode Authentication.

jdbc:sqlserver://%DB_IP%:%DB_PORT%;SelectMethod=cursor;DatabaseName=dbname

It doesn't work For window authentication using credential "MSSQLDomainusername" i.e "abcusername", using following url

jdbc:sqlserver://%DB_IP%:%DB_PORT%;SelectMethod=cursor;integratedSecurity=true;DatabaseName=dbname;

Gives following error. Login failed for user ''. The user is not associated with a trusted SQL Server connection.

I have tried adding property Trusted_Connection=Yes to url, but still gives same error. I don't want to map the drive of the SQL Server. I am able to access the any shared folder of the SQL Server Machine by providing "MSSQLDomainusername" and password.

It works fine for both authentication mode, if both machine is in same domain. If I am using jtDS Driver from the machine which is not in domain or in "xyz" domain within same network i.e same subnet, it works fine.

Answer 1

This is the deliberate and correct behaviour of Windows Authentication.

It is because the Domain from which you are connecting from, is not the same Windows Domain as the one where your SQL Server instance resides.

I believe there are methods for bridging the Domains so to speak, however they require custom and tricky implementation. You also will have to configure a trust relationship between the domains.
