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.
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
