Hi all,

We have here two types of passwords, normal and OTP. OTP authentication
should be valid for normal password services, but not the other way
around.

For that I've created two realms: EXAMPLE.COM and OTP.EXAMPLE.COM with
one way cross realm authentication. While it seems to generally work, I
would like to know if it's the correct way to do this. And if it might
have some problems with services wanting [email protected] but getting
[email protected]. And if so, is there some way to solve this?

The second problem I have, is that I want to use normal password from
inside a specific network, but OTP from outside. My thoughts here were
to prevent the EXAMPLE.COM kdc from giving initial tickets from outside
the network. Either by using a different kdc to answer outside requests
with all users have the -allow_tix attribute, or by using a preauth
plugin that refuses outside-the-network users (though for now it seems
that the preauth plugin API doesn't provide this information (please
correct me if I'm wrong)). 

Are these solutions reasonable? is there already a proper way to achieve
this?


Thanks in advance,
    Yair.
