What is an Orphaned User in SQL Server?
An orphaned user in SQL Server is a database user who has been created without an associated Windows login. This occurs when a Windows login is deleted, but the corresponding database user is not removed. If an orphaned user is left in the database, it can cause a variety of issues, such as the inability to access the database, security risks, and database performance issues.
Recognizing Orphaned Users
The first step in fixing orphaned users in SQL Server is recognizing that they exist. To do this, open the SQL Server Management Studio (SSMS) and connect to the database instance. Then, right-click on the Security folder in the Object Explorer and select “New Login.” This will open the Login – New dialog box. In the Login name field, enter the name of the user that you suspect is orphaned. If the user does not appear in the list, then it is likely an orphaned user.
Resolving Orphaned Users
Once you have identified an orphaned user, you need to resolve the issue. The easiest way to do this is to create a Windows login with the same name as the orphaned user. To do this, open the Computer Management console, right-click on the Local Users and Groups folder, and select “New User.” Then enter the same username as the orphaned user, and click “Create.”
Assigning Permissions to the Orphaned User
Once the Windows login has been created, you need to assign the appropriate permissions to the orphaned user. To do this, open the SQL Server Management Studio (SSMS) and connect to the database instance. Then, right-click on the Security folder in the Object Explorer and select “New Login.” Enter the name of the Windows login that you just created, and click “OK.” Now you can assign the appropriate permissions to the user.
Removing Orphaned Users from the Database
Once you have assigned the appropriate permissions to the orphaned user, you can remove them from the database. To do this, open the SQL Server Management Studio (SSMS) and connect to the database instance. Then, right-click on the Security folder in the Object Explorer and select “Delete.” Enter the name of the orphaned user and click “OK.” This will remove the user from the database.
Preventing Orphaned Users
In order to prevent orphaned users in the future, be sure to always delete the corresponding Windows login when deleting a database user. Additionally, it is a good practice to regularly check the database for orphaned users. This can be done by opening the SQL Server Management Studio (SSMS) and connecting to the database instance. Then, right-click on the Security folder in the Object Explorer and select “New Login.” Enter the name of the user that you suspect is orphaned. If the user does not appear in the list, then it is likely an orphaned user.
Conclusion
Orphaned users in SQL Server can cause a variety of issues, such as the inability to access the database, security risks, and database performance issues. To resolve this issue, you need to create a Windows login with the same name as the orphaned user and assign the appropriate permissions. Once this is done, you can then remove the orphaned user from the database. Additionally, it is a good practice to regularly check the database for orphaned users in order to prevent this issue in the future.
