How do we go about installing the ADL agent so that we can have our Linux boxes connected to the DS server?
If you go into the eXpress share then browse out to the agents\adlagent folder you will find a .bin file. The .bin files there need to be manually copied down to and run on the Linux machines. Linux does not allow for a remote push of software by default like the Windows machines. Running the .bin file should allow you to have the agent installed correctly.
