WLC with ACS

[Dreadgonfly]

I have installed WLC on my network and using certificate authentication with tkip encryption.Some users are able to authenticate and have access to the domain while others are not.If I log into into the same laptop with my profile,I get wireless connectivity while a user(owner of the laptop can't).Dell laptops are company standard.What could be causing this problem?Please help...

What authentication mechanism are you using? If it is EAP-TLS then each user will need their own certificate.

I would push out User Certificates via GPO.

I am using WPA authentication with Tkip.I generated my own certificate from ACS box.

WPA is your encryption mechanism, your authentication would be EAP-TLS, PEAP, EAP-Fast, LEAP, EAP-TTLS etc

PEAP thanks

what error message are you receiving on your radius server?

Encryption mismatch.On a device,connectivity starts and within 25-30 seconds,it stops.Only encryption status reverts to AES which we don't support for this setup.
