I have a number of customers that are using IBM cloud for PAW/PAFE/TM1/... Clients like Architect and Perspectives need to be accessed using a remote desktop to the remote environment. IBM sends these files (for Windows, Linux,...) with predefined settings into it, like where to connect to, etc. Upon double click on the file you will be asked for username and password, like e.g.
Not only do we need to change to a different account, we need to enter domain, account, password. You understand where I want to go to

I tried this with a number of variations but I always get the prompt.
I also looked at KeePass to store the credentials and open the rdp from KeePass. While I can do that for other remote desktop connections, these IBM remote connections typically don't work for me in the same way.
Did someone find a way to adjust the file such that a double click is sufficient to get in ? Thanks !
