Note For optimal connection performance, you should set the portNumber when you connect to a named instance. Caution For security purposes, you should avoid building the connection URLs based on user input. Note Although the previous example uses a username and password in the connection string, you should use integrated security as it is more secure. Submit and view feedback for This product This page.
Skip to content SQL Server authentication vs. Windows authentication: Which to use and when. Tweet Share Share. Establishing a connection It all starts with a connection. In order to establish a successful database connection, the client or application requires the following information: SQL Server fully-qualified domain name Instance name Port number Credentials username and password for authentication For example, suppose you use online banking.
SQL Server provides two modes of server authentication: Windows authentication SQL Server and Windows authentication mode mixed-mode You can define these authentication methods during the installation of SQL Server, or change them later via a restart. Enforce password policy : The administrators can check this option to implement the Windows password policy for SQL Server logins.
It includes specifying password length and complexity. Enforce password expiration : You can enforce the maximum age of a password.
The password will be expired and needs to change as defined by the age criteria. User must change password at next login : The administrator assigns a password during SQL login creation. Once the user logs in with their credentials, they need to specify a new password, and the administrators will not be aware of this new password. If you have multiple SQL Servers, it might be difficult for the user to keep track of the passwords for each instance. SQL Server stores the password in the master database in encrypted hash form.
Hackers can steal the information by accessing the database. Since these encrypted credentials need to be passed over the network, this can increase the chances of user credentials being stolen. You cannot implement additional customized account policies with the SQL Server authentication logins.
It increases the task of login management for database administrators. Database administrators do not have a central management console for managing logins across all instances. You might get orphan user issues when moving a database to different instances, and it might happen due to a SID mismatch in the master and user database on the new instance. You need to manage the security policies for each SQL login. I configured a port dedicated the sql server instance to alleviate the need for an instance name - just something I do.
Instead, use the jtds jdbc driver. 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 able to solve the issue with help from this and other forums. Here is what I did:. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Add a comment. A login has nothing to do with the databases. Instead, login is mapped to a user in a database to read or write to a particular database. Windows authentication mode enables local Windows authentication with SQL Server, where you can login with your local Windows credentials. Windows authentication is the default authentication mode and is more secure than SQL Server authentication. It is also referred to as integrated security which is tightly integrated with Windows.
Users who are already authenticated with Windows and need not provide any additional credentials while connecting to SQL Server. It is also called a trusted connection. The user account is confirmed by Windows. In Windows authentication, login can be created in SQL Server for an entire Windows group which simplifies managing account administration.
Windows authentication uses Kerberos security protocol, provides password policy enforcement, and supports password expiration. Let's see how to create a new login that uses local Window's user account to connect with the SQL Server.
