We have an Aruba Clearpass along with Aruba WLCs. Guest users come up on the wireless network and hit a landing page where the sign-in to the network. They in put their information, hit submit, and get the screen with the login button. When they hit the login button, though, they're sent back to the sign-in screen. There are no errors presented to the EU.
In the Clearpass Policy manager, I see that the user's login has been rejected. The alert is typically that the user's account has expired/disabled. These are users that are working just fine one day but not the next and without anyone even logging into Clearpass. I had one this morning (Monday) after being out of the facility for 3 or 4 days at least.
To fix it, I went into the endpoints database (Identity/Endpoints) and remeoved his MAC address from the cached address list. There are upwards of 18,000 in there, most listed as Unknown/Unprofiled. This user's was listed as Known but unprofiled and he was listed as offline.
There was previously a timeout of 5 minutes on the caching that Aruba recommended we drop to 1 minute; I actually dropped it to 15 seconds. This user made attempts that aree under a minute to as many as 9 minutes apart.
Any suggestions?
