[Samba] 2 factor authentication with samba

[Christian]

Hi,

has anyone experience using 2 factor auth with samba?
I just search for a stable/production ready solution, preferred with otp 
dongles.

I have searched through the list archives but couldn't find anything 
usable.
Google just gave me some links to Univention Corporate Server with 
LinOTP.

Has anybody ever done such a setup with samba? And could give me any 
hints?


Best Regards,

Christian
