What are the limitations of the personal gatekeeper?
The gatekeeper is run with your own credentials and should not be run under root. We recommend to use it for testing purposes and switch to a Grid execution service provided by other Grid middleware. Additionally, the protocol used in the personal gatekeeper is only portable to Globus Toolkit protocol 2.0. However it shoudl still be able to use it with the classical Grid services in GT3 and GT4.
