Can't get cvs checkout for src and ports as a normal user to work

Hi, i'd trying to make a checkout of the sources and ports to my fresh openbsd 6.1 install, following this guide https://www.openbsd.org/anoncvs.html but when i try to make the checkout i get some errors.

I did this steps as root:
# user mod -G wsrc usuario
# cd /usr
# mkdir -p xenocara ports src
# chgrp wsrc xenocara ports src
# chmod 775 xenocara ports src

And as a normal user:
$ cd /usr
$ ls -la
total 92
drwxrwxr-x 18 root wsrc 512 Sep 12 11:32 .
drwxr-xr-x 13 root wheel 512 Sep 8 13:50 ..
drwxr-xr-x 7 root wheel 512 Apr 1 17:06 X11R6
drwxr-xr-x 2 root wheel 5632 Sep 8 13:45 bin

drwxrwxr-x 2 root wsrc 512 Sep 12 11:32 xenocara

But, when i try to cvs checkout:
$ cvs -qd anoncvs@obsdacvs.cs.toronto.edu:/cvs checkout -rOPENBSD_6_1 -P src
