Scenario: An administrator configured an LDAP authentication policy and bound it globally.The only system group configured on the Netscaler is NS_Admins. After reviewing the security logs, the administrator notices that users in the External_Contractors LDAP group are able to log on to NetScaler using SSH; however, members of the External_Contractors group are NOT authorized to run any commands.Which action could the administrator take to prevent the members of theExternal_Contractors LDAP Group from logging on to NetScaler using SSH without affecting other users?

A. Configure an authorization policy that allows logon only by members of the "External_Contractors" LDAP Group. Bind the new policy globally.
B. Specify (memberOf="CN=External_Contractors, CN=Groups, CN=example, CN=com") as a filter in the properties of the configured LDAP server.
C. Specify (!(memberOf="CN=External_Contractors, CN=Groups, CN=example, CN=com")) as a filter in the properties of the configured LDAP server.
D. Create a new command policy with a DENY action. Create a System Group named "External_Contractors" and assign the new command policy to the External_Contractors group.
