I was using a SQuirrel SQL Client to connect & browse my oracle database servers. I have given the credentials in the connection URL itself. But it still prompts for the username and password. Does it really required to provide additional username/password while establishing connection. Won't it take it from the connection URL?
jdbc:oracle:thin:username/password#my.oracle.server.domain.com:1521:DBName
Thin driver
Oracle's JDBC Thin driver uses Java sockets to connect directly to Oracle. It provides its own TCP/IP version of Oracle's SQL*Net protocol. Because it is 100% Java, this driver is platform independent and can also run from a Web Browser (applets).
There are 2 URL syntax, old syntax which will only work with SID and the new one with Oracle service name.
Old syntax
jdbc:oracle:thin:#[HOST][:PORT]:SID
New syntax
jdbc:oracle:thin:#//[HOST][:PORT]/SERVICE
On new syntax SERVICE may be a oracle service name or a SID.
There are also some drivers that support a URL syntax which allow to put Oracle user id and password in URL.
jdbc:oracle:thin:[USER/PASSWORD]#[HOST][:PORT]:SID
jdbc:oracle:thin:[USER/PASSWORD]#//[HOST][:PORT]/SERVICE

Refer to this link, it will help you.
https://jdbc.postgresql.org/documentation/use/#connection-parameters
For example, if you want to include username & password in the Postgres connection string.
jdbc:postgresql://postgres-10.4.cluster:5432/default?user=postgres&password=postgres
Won't it take it from the connection
URL?
I think No
You need to enter usrename & password.
Check: http://squirrel-sql.sourceforge.net/user-manual/quick_start.html#howtoconnect
section Connecting
From what I have seen, support for passing the username/password in the JDBC URL is inconsistent across Oracle JDBC Drivers.

I am trying to connect to my database using JDBC driver. I have to use my another windows domain credential to connect and getting login failed error. Thought of testing it with my actual windows credential and it worked. I have used integratedSecurity = true.
String connectionUrl = "jdbc:sqlserver://server;databaseName=DB;integratedSecurity=true";
My desired connection string to use my another windows domain credential looks like the below:
String connectionUrl = "jdbc:sqlserver://server;databaseName=DB;user=domain\\user;password=test!123;"
I did the following things and in need of help:
Placed the sqljdbc_auth inside jdk/bin and jre/bin
SQL Server has been kept under the mixed auth mode (both Windows and SQL Auth).
Using my another domain ID, I tried to execute a query in MS SQL Studio and it worked.
Using the Microsoft JDBC driver, you can:
Connect with SQL Auth, using user and password
Connect with Window Auth, using integratedSecurity=true, which will use the Windows user that is running the Java program
Connect with Kerberos Auth, but that is complex to setup: Using Kerberos Integrated Authentication to Connect to SQL Server
If you want to do a simple NTLM connect using domain, user and password, then you need to use the jTDS JDBC driver.
I want to be able to connect to a SQL Server using jdbc and windows authentication.
I saw some answers on the internet saying i should add the following property to the connection string:
integratedSecurity=true;
And also add
sqljdbc_auth.dll
To the java path.
But this, as far as i understand applies only when i'm connecting from a Windows machine.
When i try this on a Linux machine i get:
java.sql.SQLException: This driver is not configured for integrated authentication
My question is how do I do it from a Linux machine.
Thanks
Well, eventually I answer my own question:
This is not possible to use Windows authentication from a linux machine using the Microsoft JDBC driver.
This is possible using the jTDS JDBC driver using the following connection string:
jdbc:jtds:sqlserver://host:port;databaseName=dbname;domain=domainName;useNTLMv2=true;
Thank you all for all the comments
TL;DR
It is not possible to use native Windows Authentication for JDBC connections to MSSQL from a JVM running on Linux.
This MSDN article explains the authentiation methods with JDBC on Linux, potential errors, and available options:
https://blogs.msdn.microsoft.com/psssql/2015/01/09/jdbc-this-driver-is-not-configured-for-integrated-authentication/
...in the JDBC 4.0 driver, you can use the authenticationScheme
connection property to indicate how you want to use Kerberos to
connect to SQL. There are two settings here.
NativeAuthentication (default) – This uses the sqljdbc_auth.dll and is specific to the Windows platform. This was the only option
prior to the JDBC 4.0 driver.
JavaKerberos – Makes use of the Java API’s to invoke kerberos and does not rely on the Windows Platform. This is java specific and not
bound to the underlying operating system, so this can be used on both
Windows and Linux platforms.
...
The following document outlines how to use Kerberos with the JDBC
Driver and walks through what is needed to get JavaKerberos working
properly.

For those who are using DBeaver the way to connect to the SQL Server Database is:
In order to connect to the SQL Server from Linux Debian using DBeaver
1.- Select SQL Server jTDS driver
2.- Enter the connection information
3.- Go to Driver Properties tab and add the domain, user, password
Just as a note, in some post I found that they needed to change the property USENTLMV2 to TRUE but it worked for me either by putting the USERTLNMV2 in true or false.
A problem that I found was that when I was trying to connect to the database using my user and password the next error was thrown:
Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.
This error was thrown because of my user was about to expire. I tried with another AD user and it could connect.
I know this is kind of an older topic but in case Google sends people here:
There are two main JDBC drivers for SQL Server. One is from Microsoft and the other from jTDS. jTDS can, amazingly, connect using Windows auth (NTLM) from other platforms, including Linux, as described here: http://jtds.sourceforge.net/faq.html#windowsAuth. It can, of course, also use SQL-authenticated logins. SQL-authenticated logins are no harder to use from any OS than any other, so don't forget about those an option.
The version provided by Microsoft is the one from which #mjn provided a quote from the documentation. It is able to connect using Windows authentication by specifying integratedSecurity=true, authenticationScheme=javaKerberos, and authentication=NotSpecified.
It is tricky to get this working even if you don't go out of your way to find more confusion, so always keep in mind which driver you are using - and tell us in these posts so that you can get more specific help.
This JDBC URL is validated to work with latest Microsoft SQL Server JDBC driver:
jdbc:sqlserver://[server]:[port];database=[db\;trustServerCertificate=true;integratedSecurity=true;user=[user without domain];password=[pw];authenticationScheme=NTLM;domain=[domain];authentication=NotSpecified
Example:
jdbc:sqlserver://mysql.myorg.com:1433;database=mydb;trustServerCertificate=true;integratedSecurity=true;user=myuser;password=mypwd;authenticationScheme=NTLM;domain=ad.myorg.com;authentication=NotSpecified
I was able to connect to a SQL Server 2016 Data Mart and JDBC connection Microsoft JDBC Driver using Windows Authentication using the following script on a Ubuntu Linux Docker Image running on Windows 10.

I have a remote MySQL database that I can connect to with MySQL Workbench (screen shot below), but I ultimately need to connect to it via JBDC and everytime I try to connect, it throws an exception. I'm new to this, so could anyone provide me some insight on what could be wrong?
String host = "testdb.db.10682960.hostedresource.com";
String datab = "testdb";
String url = "jdbc:mysql://" + host + ":3306/" + datab;
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection(url, datab, "password");
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server.
Edit: Not sure if this is relevant or not, but I'm running this on Android.
It looks like you're missing a user name. Try adding "?user=testdb" to the end of your url.
Edit: I didn't realize this was an Android app. Technically, it should be possible, but not advisable. Your network connection would be much less reliable, and you would be pushing server credentials out to your client. Use of a REST API to communicate from your Android to a web server in the same data center as the database is a much safer option.
I don't have experience trying this from Android... so I don't know what exception would be thrown if, for example, you can't reach port 3306 from the Android's connection to the network. Even if you get it working, though, do look into using a web service instead.
According to the jTDS FAQ (http://jtds.sourceforge.net/faq.html) the format of a JDBC URL is:
jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]
If I were you, I would replace the '?' with a ';' to adhere to the above format. The "query string" is not like that of a "normal" URL.
This, of course, assumes that you are using the open source JDBC connector found via the link above.
I am using the jTDS driver in order to connect to an SQL Server database from my Android application, which uses the Windows Authentication. As advised in the FAQs, I read the READMESSO file and as told, I placed the native SPPI library (ntlmauth.dll) in the system path (defined by the PATH system variable)
However, when I try to connect to the database using the following code:
String driver = "net.sourceforge.jtds.jdbc.Driver";
Class.forName(driver).newInstance();
String connString = "jdbc:jtds:sqlserver://192.168.56.1/MyMovies;";
Conncection conn = DriverManager.getConnection(connString);
I get the following exception:
java.sql.SQLException: Single-Sign-On is only supported on Windows. Please specify a user name.
Since you are connecting from an android device, you would not be able to get the SSO credentials required by the driver to connect to SQL server. The setting you referred to works only if the java program trying to connect to the DB is on a windows machine, which is clearly mentioned by the error message.
Unless your application has authorization based on the SSO user connecting to the DB, you should have an SQL Server user-based authentication mechanism to connect to the server and all authorization procedures should be tied to this user.
You might have to give the username also.
"jdbc:jtds:sqlserver://192.168.56.1/MyMovies;instance=SQLEXPRESS;user=foo"
I am currently investigating how to make a connection to a SQL Server database from my Java EE web application using Windows Authentication instead of SQL Server authentication. I am running this app off of Tomcat 6.0, and am utilizing the Microsoft JDBC driver. My connection properties file looks as follows:
dbDriver = com.microsoft.sqlserver.jdbc.SQLServerDriver
dbUser = user
dbPass = password
dbServer = localhost:1433;databaseName=testDb
dbUrl = jdbc:sqlserver://localhost:1433
I have zero problems with connecting to a SQL Server database in this fashion when using SQL Server authentication.
Is there any way I can retrieve the credentials of the user's Windows Authentication and use that authentication for SQL Server?
UPDATE: I know in ASP.net there is a way to set up Windows Authentication for access to the webapp, which is exactly what I am looking for, except I want to pass that token off to SQL Server for access to the database.
I do not think one can push the user credentials from the browser to the database (and does it makes sense ? I think not)
But if you want to use the credentials of the user running Tomcat to connect to SQL Server then you can use Microsoft's JDBC Driver.
Just build your JDBC URL like this:
jdbc:sqlserver://localhost;integratedSecurity=true;
And copy the appropriate DLL to Tomcat's bin directory (sqljdbc_auth.dll provided with the driver)
MSDN > Connecting to SQL Server with the JDBC Driver > Building the Connection URL
look at
http://jtds.sourceforge.net/faq.html#driverImplementation
What is the URL format used by jTDS?
The URL format for jTDS is:
jdbc:jtds:<server_type>://<server>[:<port>][/<database>][;<property>=<value>[;...]]
...
domain
Specifies the Windows domain to authenticate in. If present and the user name and password are provided, jTDS uses Windows (NTLM) authentication instead of the usual SQL Server authentication (i.e. the user and password provided are the domain user and password). This allows non-Windows clients to log in to servers which are only configured to accept Windows authentication.
If the domain parameter is present but no user name and password are provided, jTDS uses its native Single-Sign-On library and logs in with the logged Windows user's credentials (for this to work one would obviously need to be on Windows, logged into a domain, and also have the SSO library installed -- consult README.SSO in the distribution on how to do this).
This actually works for me:
Per the README.SSO that comes with the jtdsd distribution:
In order for Single Sign On to work, jTDS must be able to load the native SPPI library ntlmauth.dll. Place this DLL anywhere in the system path (defined by the PATH system variable) and you're all set.
I placed it in my jre/bin folder
I configured a port dedicated the sql server instance (2302) to alleviate the need for an instance name - just something I do. lportal is my database name.
jdbc.default.url=jdbc:jtds:sqlserver://192.168.0.147:2302/lportal;useNTLMv2=true;domain=mydomain.local
Unless you have some really compelling reason not to, I suggest ditching the MS JDBC driver.
Instead, use the jtds jdbc driver. Read the README.SSO file in the jtds distribution on how to configure for single-sign-on (native authentication) and where to put the native DLL to ensure it can be loaded by the JVM.
I was having issue with connecting to MS SQL 2005 using Windows Authentication. I was able to solve the issue with help from this and other forums. Here is what I did:
Install the JTDS driver
Do not use the "domain= " property in the jdbc:jtds:://[:][/][;=[;...]] string
Install the ntlmauth.dll in c:\windows\system32 directory (registration of the dll was not required) on the web server machine.
Change the logon identity for the Apache Tomcat service to a domain User with access to the SQL database server (it was not necessary for the user to have access to the dbo.master).
My environment:
