Victor is correct if you are using an external RADIUS server for AP Authorization. In that case, the only way that the WLC knows which RADIUS server to use is to start with the first one that has "Network User" checked. Once that box is checked, WLANs will use it after any authentication servers that are specifically listed under the "AAA Servers" tab. In that case, Local EAP will only be used as it was originally intended - if all external RADIUS servers are unavailable. And then, it will check after 5 minutes (by default) to see if any are available again.
If you are doing AP Authorization using only the local DB, then this is not an issue. If you use both the local and external RADIUS, local is checked first and then it goes to external, as Victor said. Also, the management user settings do not in any way impact this. Last, you can either use RADIUS or TACACS+ for management of a WLC - not both at the same time. Jason Boyers - CCIE #26024 (Wireless) Technical Instructor - IPexpert, Inc.
