We found a solution:

In post_tree.py (CPSForum), at line 145, we do the next changes:

                author = str(post['author'])

                posterName = author

                posterName = cgi.escape(context.getPosterName(author))

                if isinstance(posterName, unicode):

                   posterName = str(posterName.encode("iso8859-15"))

                else:

                   posterName = str(posterName)

                fullname = '<a href="javascript:void(0)" onclick="javascript:window.open(\'popupdirectory_entry_view?dirname=members&id=' + author + '\',\'wclose\',\'width=500,height=200,scrollbars=yes,toolbar=no,status=no,resizable=yes,left=20,top=30\')">' +\

                       posterName + '</a>'


instead of:

                fullname = '<a href="javascript:void(0)" onclick="javascript:window.open(\'popupdirectory_entry_view?dirname=members&id=' + post['author'] + '\',\'wclose\',\'width=500,height=200,scrollbars=yes,toolbar=no,status=no,resizable=yes,left=20,top=30\')">' +\
                       cgi.escape(context.getPosterName(post['author'])) + '</a>'


We've got problems with "posterName", because it returns an incorrectly 
encoded value.

In other hand, we've made an improve to getPosterName method:

    mtool = context.portal_membership

    + author = mtool.getFullnameFromId(post_author)

    + if not author:

    +   author = post_author

    - return mtool.getFullnameFromId(post_author)
      

    + return author


This changes gives us fullname of authenticated user or the poster name 
in case of anonymous user.
The original method only gives us the name in authenticated users.
