If the External Authentication feature is enabled at the Geo SCADA Expert server, each Geo SCADA Expert user account can be associated with a Windows or LDAP User Profile. This allows network administrators to disable Geo SCADA Expert user accounts and manage user account passwords without accessing Geo SCADA Expert - they apply changes to the Windows or LDAP User Profiles and these changes are automatically applied to the associated Geo SCADA Expert user accounts.
For a Geo SCADA Expert user account to be associated with a Windows or LDAP User Profile, the following criteria has to be met:
- The External Authentication feature has to be enabled and Geo SCADA Expert has to be able to connect with the Windows domain or LDAP server (the domain name or server address has to be correct and the network connections have to be healthy). For more information, see Using External Authentication with Geo SCADA Expert.
- In ViewX, each Geo SCADA Expert user account that is to be associated with a Windows or LDAP User Profile has to be configured to have the Use External Authentication feature enabled and configured appropriately.
To configure a user account so that it makes use of the Use External Authentication feature:
- Display the User Form.
On User Pattern Forms, the Use External Authentication and Windows/LDAP User Name properties are 'grayed out' and unavailable for use. The former property is enabled but provided for information only, as User Patterns only apply to systems on which External Authentication is enabled. The latter property does not apply to the User Pattern itself; it only applies to the User accounts for which the User Pattern provides other settings.
- Select the General tab.
- Use the Use External Authentication check box to define whether the user account is associated with a Windows or LDAP User Profile. (The check box is only available if the External Authentication feature is enabled at the Geo SCADA Expert server.)
Either:
- Select the check box to associate the user account with a Windows or LDAP User Profile.
- Specify the name of the Windows or LDAP User Profile in the Windows/LDAP User Name field.
(The field is only displayed if the External Authentication feature is enabled at the Geo SCADA Expert server.)
If the Allow login to Geo SCADA Expert with Windows/LDAP user names check box is clear in the server configuration, the Geo SCADA Expert user account has to have exactly the same name as the Windows or LDAP User Profile. For example, a Geo SCADA Expert user account named 'S Wilkins' can only be associated with a Windows or LDAP User Profile named ‘S Wilkins'. Additionally, the name of the Windows or LDAP User Profile has to adhere to the Geo SCADA Expert naming restrictions. If such a Windows or LDAP User Profile does not exist in your network, the Geo SCADA Expert user account will be unable to log on to Geo SCADA Expert (as the user account and password have to be verified against a corresponding Windows or LDAP User Profile).
If the Allow login to Geo SCADA Expert with Windows/LDAP user names check box is selected in the server configuration, the name of the Windows or LDAP User Profile does not have to match the name of the Geo SCADA Expert user account, nor does it have to adhere to the Geo SCADA Expert naming restrictions. (For more information, see Using External Authentication with Geo SCADA Expert).
If configured to do so, Geo SCADA Expert might be triggered to create a new User account automatically, as part of its external authentication process. On creation of such a User account, Geo SCADA Expert will populate the Windows/LDAP User Name field of that User account automatically, to show the name of the Windows or LDAP user that triggered the creation of the new User account in Geo SCADA Expert. For more information, see Integrate Geo SCADA Expert User Accounts with Active Directory or LDAP User Accounts, and see Provide Settings for Automatic User Creation.
Or:
- Clear the Use External Authentication check box if the user account is not associated with a Windows or LDAP User Profile. In this case, you can only disable, enable and change the password settings of the user account from within Geo SCADA Expert.
- Select the check box to associate the user account with a Windows or LDAP User Profile.
- Save the configuration.
