RADIUS Client/ supplicant or captive portal / mschapv2 pw change support

[Tobias Hachmer]

Hello list,

I know it isn't an directly FR issue but I hope that anybody on this 
list have had the questions I have now.

Is there a RADIUS Client or a captive portal/ hotspot software which 
supports changing password via mschapv2?
I know FRv3 will support this, but that's only the server side. Is 
there any software which supports password changes via mschapv2 like a 
Windows OS does with PEAP/MSCHAPv2?
For example a captive portal which tells the user via web frontend if 
his password is expired and allows him to change it also via web 
frontend?
google doesn't have any good answers for me. Maybe on this list is 
anyone who has done this before or have experience with this.

Thanks in advance,
Tobias Hachmer
