[rt-users] "No object mapping for field" when referencing the UserObject of a MembersObject...

[Ruslan Zakirov]

You need a user object loaded that represents actor - a user who
changing things. GetCurrentUser function is for command line tools
that can be executed by many users on your system, like bin/rt tool.
If you don't need mulit-user script then you can use $RT::SystemUser.
Each object you construct using ->new call needs the current user
provided as the only argument of the method.

In the script below you messing two concepts. You're trying to add
user X as member into a group acting under user X's credentials. If
user X has no rights to modify membership of the group X then he
obviously gets "permissions denied" error.
