.. have you applied section access also to your document ? if yes then add these 2 users to section access list also,
I was able to fix the problem. The security settings in the management console were set to NTSF which means that the appropriate window security permissions need to be set by right clicking the qvw document/folder and adding the appropriate user groups. It appears that in order for qlikview management console to control permissions the user group "authenticated users" must be given "read" security permissions.
