We have a Powerbuilder app that uses LogonUserW() method from advapi32.dll to authenticate a user/password against a specific domain.   It seems like some recent patches to Windows have impacted how this method works.  What we're seeing it only works for a user with admin rights.   When the Windows patches are rolled back, the method seems to work as before.

I'm wondering there are any alternatives for domain authentication that are available from a PB2017 app.

Hi, Peter - 

With the ever-increasing emphasis being placed on security as the likely cause of why this behavior has been changed in Windows, I'm not confident there is an alternative technique.

I understand why you're asking about this here and I hope someone is able to answer your question, but this is really not a PB issue. I think you'll have a better chance of finding an answer by asking for a new or alternative technique on a Windows Q&A forum.

Best wishes and good luck!
