What OS permissions do I need to run OMERO?

On all Unix-based systems including Linux and Mac OS X, OMERO clients and server can be installed and run as a regular user. In fact, trying to run the server as root is disallowed.

On Windows, the clients also don't need admin rights, but the server does. Specifically, the user running the server needs rights for starting services.

All ports used by default are above 1024 and also don't require administrator rights.

Whichever user runs the server on any platform will need READ/WRITE permissions to the omero.data.dir.
