As far as I could tell, that first password was just something so you can save information on the eDGe. All I did was type in a random password I use for low priority things.

It was on the next screen where I put in my domain\username domain password, and selected the wireless protocols they use.

If it helps, this is a copy of the settings my university provides:
General Settings:
If specific instructions do not exist for your operating system or wireless adapter software, you can use the settings below when attempting to connect to the wireless network.
* Network Name or SSID (case-sensitive): <SSID>
* Network Security or Authentication: WPA2 Enterprise
* Data Encryption: AES
* EAP Type: PEAP/MS-CHAP-V2
When prompted for user credentials, use the following:
* User Name: your username
* Password: your password
* Domain: <DomainName>
