    The error you are getting are related to the Guest user and role:

    technet.microsoft.com/.../hh527095.aspx

    But the real issue is that most likely you are not passing in a Windows Active Directory security credential when signing in I assume, or your Internet Information Services service or AX Business Connector proxy account is not configured correctly or at all. Users using your AX system must be authenticated, and using the Guest account is a bad idea.

    I would suggest going through the documentation yourself again to verify which setup step or access did you miss.

    Than you Vilmos,

    when trying to access the vendor portal with another user that has the guest role and the external portal role am getting different error as per the below, I already configured vendor portal just like TechNet steps:

    Hi Vilmos,

    Does vendor portal has to be on new web application , or it can be on existing web application used for Enterprise Portal employee services?

    Thank you,

    I cannot comment on the above question, we are using our own custom implementation of a Vendor Self-Service portal.

    Hi Vilmos,

    if I want to use vendor portal for vendors that have users on AD, and log in using VPN, any setup needed for those users(vendors) on AX other than giving vendor role on AX?

    Thank you.

    Not sure, like I said above, we have our own VSS portal where we just send out the PO number and a PIN code, with which they could see the pending orders and confirm them to book in a delivery on a specific date.

    I would recommend to have a look at the documentation, that usually clearly explains what should be done. It does not go in the details of using a VPN service, that is something for you to explore, since it belongs to infrastructure and not the AX product itself. Let us know how it goes in case you have succeeded, so other community members could learn from it if they have similar requirements.

    Thank you.
