After authenticating into AccessPoint, the portal attempts to lookup the displayName property of the authenticated user via the configured Directory Service Provider on the DSC, You can associate your Domain with the default AD provider, or with the label of the Configurable LDAP provider. The Configurable LDAP provider allows you to map the displayName property to any attribute in the directory.
OSuser() will supply the authenticated username, which may be the NTNAME in Section Access. It won't provide the displayName.
QVuser() displays the value of USERID from Section Access. Use of USERID and PASSWORD in Section Access is discouraged.
I believe you need to do two things to get full visibility of your CAL assignments. First is to enable an XML representation of the CalData.pgo files under the QlikView Server. Do this by adding PgoAsXmlAlso=1 to the [Settings 7] section of C:\ProgramData\QlikTech\QlikViewServer\Settings.ini then restart your QlikView Server.

Then you want to match the Domain\UserID from the PGO files to data in your Active Directory. There are several ways of reading AD from within QlikView. You can use the Microsoft logparser utility to extract to CSV, or use the AD OLEDB driver directly within QlikView Script, or use a Custom Datasource Connector.
