Information
This security 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. Validation of each request for a session ticket is optional, because the extra step takes time and it may slow network access to services.
The STIG recommended state for this setting is: Enabled.
Rationale:
If this policy setting is disabled, users might be granted session tickets for services that they do not have the right to use.
Impact:
None - this is the default behavior.
Solution
To establish the recommended configuration via GP, set the following UI path to Enabled:
Computer Configuration\Policies\Windows Settings\Security Settings\Account Policy\Kerberos Policy\Enforce user logon restrictions
Default Value:
Enabled.
