Security Related Dialogs
There are variety of security-related messages that you may encounter while working with VTScada.
Several situations may force you to change your password: If passwords expire on a set time interval, if a security account manager has changed the minimum password requirements, or if the manager has set an option that requires you to change your password. (Expired passwords will always work one last time to give you the opportunity to use the Reset Password dialog.)
Provide your old password to confirm your identity (note that passwords are case-sensitive) and then enter a new one. You are required to type the new password twice to minimize the chance of a typo being saved in the new word.
Old Password is Incorrect Dialog
The reset password dialog requires the user to verify their identify by typing their current (old) password before entering a new one. If an incorrect word is entered for the old password, the following dialog will appear.
Click on the Close button and type the correct old password to proceed.
If the application has been configured to warn users that their password will expire in the near future, then every time they sign in during the configured warning period the warning dialog will appear, showing the number of days until they must set a new password.
In the event that you are not signed in and you attempt to access a control process (for example, if you attempt to close your VTScada application by clicking the Windows close button at the top of the Display Manager), or try to control machinery, you will receive an access denied message similar to the following:
Sign in to the application using your username and password, and then attempt the control process again.
If you are signed in to your application, and attempt to access a control process for which you are not authorized, you will receive an access denied message similar to the following:
The dialog shows that you do not have the privilege appropriate to the action you've just attempted to complete. If you find that the action is necessary to your duties as an operator, please speak with your VTScada developer, or the person in charge of the security for your application so that they can add the appropriate privilege to your user account.
Access Denied: No Application Close Privilege
If you have not been granted the appropriate user privilege, and you attempt to close the application using the Windows close button, you will receive the following access denied message:
If you receive the above dialog, you will be unable to close the application using the Windows close button. You must use the VAM to stop the application.
When you are in the process of changing your password, and the password you entered in the New Password and Confirm Password fields does not match, then the dialog opens as shown:
Close the dialog and re-enter your new password in both fields again, ensuring that you spell the password correctly and enter the exact same password in each field.
If you are creating a new password and do not use the number of characters required by the security manager, you will see this dialog. Click the Close button, then create a new password having at least the number of characters stated in the dialog.
New Password Matches Old Password
VTScada will not allow you to create a new password that is the same as the previous password. When changing a password, you must change it to something new.
Your security manager may have configured the application to require strong passwords . These are passwords that contain numbers or special characters so that they do not match dictionary words. Click the Close button, then create a password having at least the number of special characters listed in the dialog box message.
Operation Not Permitted Message
In extremely rare cases, a message may appear that reads, "Operation Not Permitted, Account Not Modified".
When running a standard VTScada application, you will not see this message. It can happen only if custom code happened to call a security-related function using a malformed user name.
If you do see this message, please contact the developer of your customized application.
This message is not to be confused with the Access Denied message that appears whenever a user attempts to access a function for which they have not been granted privileges.
You must hold the appropriate Control Token in order to write to this tag. For reasons of safety, only one person at a time may hold any tag's control token.
Request the token by clicking the button provided by the application developer.
