Vulnerability discussion

This setting controls the signing requirements for LDAP clients. This setting should be set to Negotiate signing or Require signing depending on the environment and type of LDAP server in use.

Check content

Analyze the system using the Security Configuration and Analysis snap-in. Expand the Security Configuration and Analysis tree view. Navigate to Local Policies -> Security Options. If the value for “Network security: LDAP client signing requirements” is not set to at least “Negotiate signing”, then this is a finding. The policy referenced configures the following registry value: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \System\CurrentControlSet\Services\LDAP\ Value Name: LDAPClientIntegrity Value Type: REG_DWORD Value: 1

Fix text

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “Network security: LDAP client signing requirements” to “Negotiate signing” at a minimum.
