I have added the new servers to /etc/raddb/clients.conf in the same way as the ISA servers were, and entered a shared secret (simple to try and help debug this).  I have then added the same servers to my clients list in MS IAS with the same shared secret.

> Ar Dachwedd y 1af 2011 newidiodd UWIC ei henw i Brifysgol Fetropolitan Caerdydd. O Ragfyr 6ed, fel rhan o'r newid yma, bydd pob cyfeiriad e-bost sy'n cynnwys @uwic.ac.uk yn newid i @cardiffmet.ac.uk. Bydd yr holl ebyst a ddanfonir o Brifysgol Fetropolitan Caerdydd yn cael eu danfon o‘r cyfeiriad @cardiffmet.ac.uk newydd. Gwnewch yn siwr eich bod yn diweddaru eich cofnodion cyswllt a'ch cronfeydd data i adlewyrchu hyn. Gellir cael rhagor o wybodaeth ar y wefan yma.
