What is ?Dual administration??
This is a security measure that allows you to specify if the approval of two administrators is required when making approval limit changes or any increases to user permissions in the User Admin section. Dual administration is set on individual users so it is possible to have some administrators that operate under single administration and others that operate under dual.
Where dual administration is on, we recommend you have at least three administrators, so that you have back-up if one administrator is not available.
