How security authenticates user accounts

When a user attempts an action that is secured, security authenticates user names and passwords in this order:
  1. Against the list of
    FactoryTalk
     user accounts. If a match is found, the user is allowed to proceed.
  2. Against the list of
    Windows
    -linked user accounts. If a match is found, the user is allowed to proceed.
  3. Against the list of accounts in a
    Windows
    -linked user group. If a match is found for the user name and password in a
    Windows
    -linked user group, the user is allowed to proceed, even if no
    Windows
    -linked user account is present for that user.
To prevent some users in a
Windows
-linked group from having access to the
FactoryTalk
 system, create
Windows
-linked accounts for those users, and then set permissions to deny access to those user accounts.
