Does this apply to an admin user account that is used by an external BOI process?

How long do password remain valid before a required change?

Yes, I dont know to be honest, how can I check that? User credentials were given by Sage admin to me and I build an integration . as I said it was working well , but now BOI still thinking password is expired, but it was already changed.

Your BOI connection asks for user and password as part of your code. Check your script.

what do you mean? the problem that i got a message "password expired" when I set user to oss. FUn part that now i have ccreated completely new user, and I still having same error.

Greetings,

 Please have the Sage admin that gave you the credentials validate that they can logon to Sage 100 with that user and password and that the proper role has been assigned to the user in Sage 100.  If the user is setup properly in Sage 100 and the company has the Allow External Access flag set and your code is connecting to the same Sage 100 instance, then BOI should allow access.

I did notice one thing in your code which is that you have the Logon() method and SetUser() methods reversed.  Typically, they should be like the following.

using (dynamic sySession = pvx.NewObject("SY_Session"))
{
     int result = sySession.nLogon();
     if (result == 0)
     {
          result = sySession.nSetUser("username", "userpassword");
          if (result == 0) throw new Exception(sySession.sLastErrorMsg);
     }

}

Thanks,
Kent
