Because Kerberos can be a complex environment to set up and maintain, it is important to have qualified support at your site. Authentication of the user ID is done through the use of Kerberos in the operating system.
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. You cannot define a universal policy for all accounts in your organization.
For a large database footprint, it is an arduous task to define the policy for each individual login. Best use cases for SQL Server authentication It can help older applications and third-party software connect databases if they do not support Windows AD authentication.
You might require users from untrusted domains to connect to SQL Server. In this case, the application can specify SQL logins in the connection strings and connect to the database. It can help SQL Server to support web applications where users create their own identities. This connection pooling is not a good practice. In this case, you can create separate logins for each user and connect to the database using their credentials. By default, if you implement SQL Database in the cloud, i.
Later, if required, you can configure AD-based authentication. You can use it to connect from cross-operating systems such as Linux and macOS. An overview of Windows authentication In Windows authentication, the user should first authenticate himself within Active Directory. Advantages of Windows authentication Windows authentication is a secure way of connecting to SQL Server, and it uses the tokens and SPNs for authentication purposes using the Kerberos authentication protocol.
Therefore, it does not send passwords across the network, and it safeguards stealing passwords across the network. It uses Kerberos security protocol, and you can implement password policies such as complex passwords, account lockouts and password expiration. This password policy can be implemented at the organization level across all servers. Therefore, you can control user security policies at the organization level instead of at the individual login level like with SQL Server authentication.

Entering a value here or on the client side overrides this default process. Right-click the Logical Workspace Server and select Validate.
If the connection fails, verify the following: The object spawner's start-up command includes -sspi. If the workspace server runs on UNIX, the prerequisite steps have been successfully completed see step 1 above. After the connection succeeds, examine the object spawner log to verify that the connection to the workspace server was made using IWA.
If the spawner log indicates that credential-based authentication occurred instead of IWA , the user's context includes credentials for the workspace server's host. Note: Even if IWA is configured, any available cached or stored credentials are preferentially used.
If the workspace server is on Windows and needs to access Windows network resources such as UNC pathnames or IWA connections to databases : Edit the Security package list so that only Kerberos is specified. In Active Directory, make the object spawner account trusted for delegation. See Windows Privileges. In general, users shouldn't make changes to the advanced IWA settings in their client-side connection profiles. The format of the stored user IDs must match the format in which authenticated user IDs are returned to the target server.
If the target server is on UNIX, the authenticated user ID is returned in short format it is not qualified , so the stored user ID should not be qualified for example, joe or fred. You need to distinguish between two different users, in two different Kerberos realms, who happen to have the same sAMAccountName name for example, joe US. These instructions assume that you have already fully configured IWA. Note: You can't use Windows local accounts with this configuration, because those accounts can't use Kerberos.
If the spawner runs as a service, complete these steps:. From the object spawner's configuration directory, enter the following: ObjectSpawner. Also, make sure that the -sspi setting is present.
