2 factor authentication

[Alonzo Vera]

Hi,

I have a subversion server at work that is accessed via ssh and rsa keys. This has been working fine with Tortoise. Recently there has been a request to implement in addition 2 factor authentication. Tortoise seems to have problems dealing with the additional challenge. When using the verbose mode I can see that the key challenge is passed, but the process hangs and is reset in the middle of the next authentication challenge. It is funny because you can see (using plink) that the message from the server asking for the next authentication is truncated. In the server I can see that the client (tortoise) is the one reseting the connection. Anyway, has anybody had any luck with a similar scenario? We are using google authenticator app on the server for the 2-factor authentication.
