Using NNTPS with tin

Hello gentlemen,

I would like to read secure news (i.e. nntps://snews.gmane.org/)

I thought that I could read news using combination of socket and openssl
for wrapping secure traffic.

I connected to NNTPS and forward connection to local port with a command:

$ socket -p "openssl s_client -connect snews.gmane.org:563" -s 10000

then I try to connect with tin to my local port with a command:

$ tin -g localhost -p 10000

I got output like:

__output__
Reading config file...
Connecting to localhost:10000...
depth=0/C=NO/ST=Some-State/L=Oslo/O=Gmane/CN=snews.gmane.org/[email protected]
Reading input history file...
Reading mail active file...
Reading groups from active file...
__tin exits__

Basically I can telnet to localhost:10000 and execute NNTP commands 
(like "list newsgroups").
But I still cannot figure out why tin cannot do the same.
(somebody reported that it can be done with GNUS)

Could you point me to the right direction to dig?

Best Regards,
Andrei
