Say I have 20 or so user groups with in ACS and I want to modify one field in all of them (say I want to change the [3076\005] Primary-DNS field in all of them to have the same). Is there a way to do this in one shot (either through upload a txt using csutils??) or would I need to edit this one group at a time?
There is an Action Code (163 - ADD_RADIUS_ ATTR) in RDBMS, but it would only modify IETF RADIUS Attributes.
I don't beleive there is any option to accomplish what you are trying to do...
You will need to go one by one into each Group and make the required changes.
