The K2 Server is unable to correctly resolve users from groups when the users are members of multiple groups that have names containing the '@' character.
Therefore, for a process that can be started by users from a group that has a name containing the '@' character, on a system that those users are members of other groups that contain the '@' character, the K2 Server is unable to resolve users and returns a "[User] does not have rights to Start [Process]" error.
