ANT + CVS (ext)

Hi guys,
I'm trying to checkout from a CVS server (ext) some sources with ant (with cvs task and cvspass task) and I want to do this automatically(not to enter the password every time). I'm using Tortoise cvs client and for the ssh comunication I'm using TortoisePlink.exe.The problem is that it works but I have to input the password every time for TortoisePLink (it doesn't matter that I'm trying to use the passfile).
I tried to use instead the PLink from Putty, and I also tried without a passfile, but it seems that the only way that it works is with inputing the password for TortoisePlink every time. I tried with WinCVS also, but with that it didn't work.
If anyone has solved this problem, please help me asap!

Thanks,

Lucian

<cvspass cvsroot=":ext:user@host:/export/home/repository/das"
password="xxx" passfile="c:\.cvspass"/> <br>
<cvs cvsroot=":ext:user@host:/export/home/repository/das" command="checkout" package="java/Common" passfile="c:\.cvspass" dest="." cvsrsh="C:\Program Files\TortoiseCVS\TortoisePlink.exe" >

I solved the problem with pagent from putty.

Could you outline the exact procedure. I'm having some tough time with Tortoise CVS with binary files. So thought Ant might give a good way.

If you can ouline the exact steps that would great.
