APM Remote Desktop auto-logon without password fails

Just to add some clarity, I am using a variable assign in VPE to set the variables. I have tried setting pw variable to secure as you advised but without a change still getting negative results. I have also tested on different end point, Win 2008 R2 (server in the domain) using username and password and was able to logon without an issue. Perhaps, I have tested setting password variable to secure and insecure and both worked.
