EAP-TTLS is not supported by Windows 7 or older. However, there is a
"driver" for it from SecureW2 which was licensed under GPLv2 until
version 4.1.0 (still available on the net) but I don't know if older
systems than Windows 7 are supported.

What clients do you mean by "old"? If your oldest client is Windows XP
you can use PEAPv0/EAP-MSCHAPv2. I don't know if MAC OS supports
EAP-MSCHAPv2 (it does support PEAP however) and based on the search
results one has to use TTLS-PAP instead. At least Wikipedia states
that PEAPv0/EAP-MSCHAPv2 is supported by MAC OS.
