Validate Username/Password in DeltaV Live

Hello all,

Does anyone know a way to validate a username/password combination in Typescript without using Electronic Signatures? Something like a function that could validate if given credentials are valid.

I saw the ValidateEsig functions that are mentioned in the Script Assistant but wondering if something similar exists without using electronic signatures.

Thanks,
Stefan

  First thing to know is DeltaV uses the Windows User Authentication. It does not keep or manage its own passwords. So the question I have is, what are you actually wanting to do that you feel you need to prompt a user for his user/password information within the HMI? Maybe there is a way to do what you need to do that does not require any entry of user passwords to an HMI Script.
  
  Logging off the DeltaV user and forcing a log on would be on way of forcing a revalidation of the user. The Screen saver can be setup to auto logoff the current user, securing the console and forcing a valid user/password to gain access.
  
  The ESig allows for a re-entry of the user password to ensure the person performing the write is indeed a valid user, with an option to add a confirming user/password if needed. This is a function that passes the User Password securely to the Authentication server.
  
  What other use case are you trying to address that you need to "know" if the current user is indeed valid to do the next task? Maybe we can help find a solution to your problem rather than hack the user security of the system over a public forum...
