ACS Authentication

I have users who Are Connected on Cisco Wireleses controller ,they are connected to Wirelesses but get Disconnected also have ACS throught which authentication Happens and its Intergated with Active Directory

1)There is one user who users DELL LATITUDE 6320 and gets disconnected after 45min and checked his Logs in ACS

Problem: Error "Authentication failed : 12308 Client sent

Result TLV indicating failure"

The Authentication failed : 12308 Client sent Result TLV indicating

failure error occurs on the ACS when you try to authenticate for the first time. Authentication works fine

the second time.

Solution

This error can be resolved when you disable Fast Reconnect. An upgrade to patch 2 of ACS version 5.2

helps to resolve the issue without the Fast Reconnect being disabled.

I DSABLED THE FAST RECONNECTED BUT STILL GETS DISCONNECTED AND ALSO HAPPENING WITH OTHER USERS WITH SAME DELL MODEL

ANY HELP WILL BE APPRECIATED,THANKS IN ADVANCE

Thanks for reply, but the Controller says Dencryption error only

ACS Authentication

As the problem is only restricted to one device or one type of devices, I suggest that you upgrade wireless card's driver to latest and check.
