The following happens with both Cisco and HP switches that we have setup for port authentication using ACS for radius.
We also use Mitel phones.
Ex. we take port authentication of the switch to do mainteance and when we reapply this the Mitel phones don't authenticate and when you look at
the logs it shows weird usernames under the "usernames" section in the ACS...like "...WMT"
The way our phones are setup is we have manually entered a username and password for 802.1x while setting up the same username and pw on the ACS. We do this instead of say MAC to port authentication because phones and people move offices so much.
I'm also reaseraching Mitel but not getting very far, It would help if I know the phones were somehow offering up this username instead of the one programmed or if the ACS is defaulting to this for some reason.
