gLExec is a program that acts as a light-weight 'gatekeeper'. gLExec takes Grid credentials as input. gLExec takes the local site policy into account to authenticate and authorize the credentials. gLExec will switch to a new execution sandbox and execute the given command as the switched identity. gLExec is also capable of functioning as a light-weight control point which offers a binary yes/no result called the logging-only mode.
Current version
The latest stable version is gLExec 0.7.0-2.
