[OATH-Toolkit-help] totp pam and try_first_pass or use_first_pass

[Jens Czyborra]

Example:

in /etc/pam.d/sudo:

auth            required        pam_unix.so
auth            sufficient      pam_oath.so     usersfile=/etc/users.oath 
digits=6 try_first_pass debug

By testing the login by the unix pass everything works well.

By testing with the otp (xyzabc_ is the password and 123456 is the otp) i get:

~]$ sudo su

Sorry, try again.

the same with use_first_pass

withou both try_first_pass and use_first_pass it works but i'm asked first for 
the unix pass and second for the otp if unix fails
