Identifying User from QV in SSO implementation

[#1]

Hi All,

We, meaning mostly our consultant, set up an SSO configuration.  The user signs in to an external portal.  The portal requests a ticket from QV with the credentials of the user.  The ticket is returned, and the portal then requests a document that is included in an iFrame on the portal.  So far, so good.  The ticketing works, in that it is granting access.  We may user Section Access or we may only need the username to match on our database values.  What I can't determine is how to tell from inside QlikView what user is coming in with the ticket: both OSUser() and QVUser() return nothing in our tests. 

What is the method for extracting the user credentials from a ticket from inside of QlikView?

By the way, in our implementation, both QVUser() and OSUser() return nothing.

An update: we can see the username that has been authenticated in AccessPoint, but QVUser() is still blank in the iFrame when that is pulled up.

This is now resolved - I was using Subfield(OSUser(), ‘\’, 2) and since there was no domain, it returned null.  OSUser() is returning the correct value.
