Hi all,
as a long time LinOTP user I know
pam_linotpby heart and found it rather useful to prompt a user for an OTP and hand it over to a custom vaildator. To avoid TCP roundtrips and open ports on desktops, I added the possibility to use a UNIX domain socket for communication.I'll share this code in the hope it's useful for someone else.
