com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user

Question

I am trying to connect my java Program to our SQLServer db that I access remotely by VPN, this DB uses windows authentication. I have sqljdbc4.jar in my libraries folder in Netbeans, also a jar file in the source packages tab(Not sure why its there). I think this problem is related to the VPN because I am pretty sure of all the credentials being used.

    String url = "jdbc:sqlserver://AAAHCSQL01:1433;databaseName=netForumAAAHCDev;";
    try{
       conn = DriverManager.getConnection(url,userName,password);

    }catch(SQLException e){
        e.printStackTrace();

    }

Here's the error:

com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'MBisesi_AAAHC'. ClientConnectionId:92c25c9c-506b-4c77-88c3-819fc0774883

Answer 1

I use a VPN and have the same error for this jdbc driver. Only difference is I run SQL Server in Mixed authentication mode. I can say two things:

1. you may need to add instanceName to your connect string (see below).
2. try using jtds, its the only driver I could get to work (note my example assumes hibernate).

WORKS

<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:jtds:sqlserver://****:1433;instance=***;DatabaseName=***;</property>
<property name="hibernate.connection.username”>***</property>
<property name="hibernate.connection.password”>***</property>

DOESN'T WORK

<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="hibernate.connection.url">jdbc:sqlserver://****:1433;instanceName=***;DatabaseName=***</property>
<property name="hibernate.connection.username”>***</property>
<property name="hibernate.connection.password”>***</property>

EDIT

• Note: upgrading SQL Server 2008 R2 to SP3 did not enable the MS driver to work. Also, this link may be help.
