Back in august, attached to some cisco release notes was this:
Clients Using WPA/WPA2 and Power Save May Fail to Authenticate
Certain clients using WPA/WPA2 key management and power save can take many attempts to
authenticate or, in some cases, fail to authenticate. Any SSID defined to use authentication
key-management WPA, coupled with clients using power save mode and authenticating using
WPA/WPA2 can experience this problem.
A hidden configure level command, dot11 wpa handshake timeout, can be used to increase the timeout
between sending the WPA key packets from the default value (100 ms) to a value between 101 and 2000
ms. The command stores its value in the configuration across device reloads.
Anyone know if there's an aruba alternative to this command or where it may be/how it may be worded in the Web UI?
Also, if you know of the relevence of this command, what would you set it to, if not the default and what is the default for aruba, if different from the above?
Thanks in advance.

Cisco would have to explain what clients they are talking about for Aruba to say specifically.

I'm more on the Cisco side and only use Airwave to monitor our autonomous Cisco AP's, but I don't think I would change the default setting unless I verified that we were actually experiencing an issue. 100ms is a pretty long delay already, so if there is a setting that can be changed I would advice you increase it in small increments (say 50-100ms) until the problem is remedied.
Sorry I couldn't be more help.
