Licensing with open document

Hello,

As part of a project, we are planning to give access to a webi report by using the opendocument function and passing the session through a named account.

I have licensing concerns and want to be sure we are ok.

From my understanding (please correct me if I am wrong), a named account cannot be "generic" meaning you need a real person behind it. But in the case of open document, is it ok in terms of licensing that 10 users for example, will connect through a different application (not SAP BI) and view only a webi report?

If not, what type of licensing is required?

Thanks for your help :)
