Well,
I did found out that I have access to the lenya repository, but the problem is that I had download all the repository as anonymous user.
So, I did not want to download again the same repository, looking on the diferents it seems that on the .svn/entries change the http: to https: should be enough:
find . -name entries -exec perl -pi -w -e 's/http:/https:/g;' {} \;
That worked for me.
Cheers,

Ack! Don’t do that! Manually editing the entries file is a horrible idea, and is liable to break in strange and interesting ways.
To switch from a http checkout to a https checkout you can simply use the ‘svn switch –relocate’ command, like so:
$ cd /path/to/working/copy
$ svn switch –relocate http: https:
uppsss…
I did a commit and it worked. So I thought that it was enought.
svn cleanupsvn switch –-relocate https: http:svn switch -–relocate http: https:looks ok, yuppy!
