How to access cvs.debian.org with ssh/rsa keys?

[Frank Küster <frank@debian.org>]

Hi all,

I've recently been given write access to the tetex directories on
cvs.debian.org, but it seems when I login, the password is blown over
the net in plaintext.

I have put my rsa key into the LDAP system, and can login e.g. into
gluck with ssh. Since the key is protected by a password, I'm asked this
password, but then the question asked is:

Enter passphrase for key '/home/frank/.ssh/id_rsa': 

I have set CVS_RSH=ssh, and I try to access the cvs with 

cvs -d :pserver:frank@cvs.debian.org:/cvs/tetex login
Logging in to :pserver:frank@cvs.debian.org:2401/cvs/tetex
CVS password: 

This doesn't look like ssh authentication. What am I doing wrong (or
what should I have read)?

TIA, Frank
