SecurityAgent Logon Error - 10.7.5 update
Seeing this issue (again) after updating from 10.7.4 to 10.7.5 on MacBook Pro.
It occurs when a non-admin AD user attempts to login over PEAP wireless (WPA2 Enterprise).
The error is:
"SecurityAgent wants to make changes. Type an administrator's name and password to allow this."
This is a client, and not a server issue, but it may only affect enterprise setups, so I believe that is how the issue was filed here.
The issue is resolved by downgrading the MacBook Pro to 10.7.4.
MacBook Pro, Mac OS X (10.7.5)
