+# Enforce user logon restrictions
+
+**Applies to**
+-   Windows 10
+
+Describes the best practices, location, values, policy management, and security considerations for the **Enforce user logon restrictions** security policy setting.
+
+## Reference
+
+The **Enforce user logon restrictions** policy setting determines whether the Kerberos V5 Key Distribution Center (KDC) validates every request for a session ticket against the user rights policy of the user account. Validating each request for a session ticket is optional because the extra step takes time, and that can slow network access to services.
+
+The possible values for this Group Policy setting are:
+
+-   Enabled
+-   Disabled
+-   Not defined
+
+### Best practices
+
+-   If this policy setting is disabled, users might be granted session tickets for services that they do not have the right to use.
+
+    We recommend to set **Enforce user logon restrictions** to Enabled.
+
+### Location
+
+**Computer Configuration\\Windows Settings\\Security Settings\\Account Policies\\Kerberos Policy**
+
+### Default Values
+
+The following table lists the actual and effective default policy values. Default values are also listed on the policy’s property page.
+
+| Server Type or GPO | Default Value |
+| - | - |
+| Default Domain Policy | Enabled| 
+| Default Domain Controller Policy | Not defined |
+| Stand-Alone Server Default Settings| Not applicable |
+| DC Effective Default Settings | Enabled| 
+| Member Server Effective Default Settings| Not applicable| 
+| Client Computer Effective Default Settings | Not applicable| 
+ 
+## Policy management
+
+This section describes features, tools, and guidance to help you manage this policy.
+
+A restart of the device is not required for this policy setting to be effective.
+
+### Group Policy
+
+Client devices will get the new setting during the next scheduled and successful Group Policy refresh. But for domain controllers to assign these new settings immediately, a gpupdate.exe /force is required. On the local device, the Security Configuration Engine will refresh this setting in about five minutes.
+
+Settings are applied in the following order through a Group Policy Object (GPO), which will overwrite settings on the local computer at the next Group Policy update:
+
+1.  Local policy settings
+2.  Site policy settings
+3.  Domain policy settings
+4.  OU policy settings
+
+When a local setting is greyed out, it indicates that a GPO currently controls that setting.
+
+## Security considerations
+
+This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.
+
+### Vulnerability
+
+If you disable this policy setting, users could receive session tickets for services that they no longer have the right to use because the right was removed after they logged on.
+
+### Countermeasure
+
+Enable the **Enforce user logon restrictions** setting.
+
+### Potential impact
+
+None. This is the default configuration.
