I'm working with Profile Manager in Lion Server 10.7.2, and Google Exchange as our exchange server.
I want the user to be prompted during the installation to enter their username, not set the value here. To have the user prompted, both fields need to be left blank. The User field, however, requires a value. There are payload variables outlined by Apple, but not all of the users' accounts are %short_name%.
In iPhone Configuration Utility the user field is optional. This looks like a change made between ICU and Profile Manager.
