https://fedorahosted.org/freeipa/ticket/1688 The serial associator is used to execute a command multiple times with different parameters. This is used for adding/removing a user into/from multiple groups. It has some issues: Each command is executed one-by-one, so it could be slow. * If there's a failure the rest of the commands will not be executed. * This can be fixed by putting the commands into a batch and execute them at once.
