wlst setRoleExpression
I am trying to use wlst to configure a security realm. I have the commands needed to create an AD provider and configure that. I am at the step where I am adding an AD group to the global Admin role. I am running command.
```python
cmo.setRoleExpression('','Admin','Grp(wl_admins)|Grp(Administrators)')
```
The issue is, I want to keep the default "Group Identity Domain has administrative rights in calling context" with Adminstrators. I am not sure what the predicate is for that. And I cannot find a good reference for this. I looked at the output from cmo.getRegisteredPredicates('*') but that did not help much. And examples of using this are lacking. Does anyone know how I would set that in the setRoleExpression method?
