i'm trying some protocol which can support centralized authentication, their will not be a need to re-authentication if we are joining for same AP.Do fast handover and support roaming.

These features can be developed if i use CAPWAP.i tried to implement using opensource code.
but getting many bugs.it is not able to join.can any one suggest me any link other than sourceforge.net for CAPWAP source code.or can any suggest me other protocol which can support all these features.

Thank you
