I'm trying to find out what these mean. I have a few users, usually with a iPhone, that will get periodically prompted for credentials with their Exchange Active Sync account.
In the application log on the UAG I see quite a few of the following:
LogName: Application
Source: Microsoft Forefront UAG
Event ID: 14
Logged 2/1/2012 6:04:43 AM
Task Category: None
Keywords: Classic
Computer: CACUAG01
I removed the domain and user name to protect the innocent. Can someone explain what causes these?
"User domain\username with source IP address failed to log into trunk exchangeactivesync (secure=1) using authentication server MSAD with session ID 6E0357C8-7196-4A30-9FD3-613839303E6A. Error code is Invalid Credentials."
