Alessandro,

I was able to reproduce your problem on my virtual machines. By that I
mean that in trying to join a 2003 domain in ADS mode, I get the exact
same error as you.

I was able to solve it as explained below.  Keep in mind that the same
error may be caused by different problems.  

My test domain name is 'DOMAIN', and my realm is 'DOMAIN.COM'.  

Setting either of the of 2 following lines caused the error indicated:
workgroup   = DOMAIN.COM
or
realm       = DOMAIN

Setting as follows, I joined the domain no problem.
workgroup   = DOMAIN
realm       = DOMAIN.COM

So it appears the domain name is the leftmost portion of the REALM, and
the REALM must be the entire name.  Anything else will fail.

So try changing your workgroup line setting it as follows:
workgroup = ARM

I believe you will then be able to join sambe to the 2003 domain.

Give it a shot and let me know.
