I'm aware this question has been asked a lot of times. I believe I understand the answers, but I still had no luck.
I tried both one repo and multiple repos configurations, having the same issue for both of them.
So, with the config I'm interested in:
<Location /svn>
DAV svn
#SVNPath /media/ssd/svn/test
SVNParentPath /media/ssd/svn
SVNListParentPath On
AuthType Basic
AuthName "Subversion Repository"
AuthUserFile /etc/apache2/dav_svn.passwd
Require valid-user
</Location>
My repository
luso@bender:/media/ssd/svn$ ls -lart
total 16
drwx------ 7 luso luso 4096 2012-09-15 16:20 ..
drwxr-sr-x 6 www-data svn 4096 2012-09-24 22:13 test
drwxrwsr-x 4 www-data svn 4096 2012-09-24 22:31 .
drwxr-sr-x 6 www-data svn 4096 2012-09-24 22:31 test2
Inside a project

the user luso and www-data are in both the svn and www-data groups. However, when /system/administration/users and groups, if I select the www-data user there is a warning: This account is disabled ¿¿?? If I try to enable it, it asks me to set a password. I didn't do it...
/media/ssd is my /dev/sdc drive (an ssd drive)
I can co using file:// protocol
luso@bender:~$ svn co file:///media/ssd/svn/test test
A test/.classpath
A test/.project
A test/target
A test/target/test-my-app-0.0.1-SNAPSHOT.jar
...
...
However,
luso@bender:~$ svn co http://localhost/svn/test test and
luso@bender:~$ svn co http://localhost/svn/test/trunk test
lead me to:
Authentication realm: <http://localhost:80> Subversion Repository
Password for 'luso':
svn: Could not open the requested SVN filesystem
more precisely
<D:error xmlns:D="DAV:" xmlns:m="http://apache.org/dav/xmlns" xmlns:C="svn:">
<C:error/>
<m:human-readable errcode="13">Could not open the requested SVN filesystem</m:human-readable>
</D:error>
Of course, the same happens if I try to access via web browser...
And the same happens if I change
#SVNPath /media/ssd/svn/test
SVNParentPath /media/ssd/svn
SVNListParentPath On
with:
SVNPath /media/ssd/svn/test
#SVNParentPath /media/ssd/svn
#SVNListParentPath On
and reload/restart apache2
Also, the same happens when trying to access via https:// which is working fine.
I've read something indicating SELinux had something to do, but I don't dare to change this. I don't really know how to...
Might it be some kind of conflict with permissions? The /media/ssd drive is owned by luso... (no idea, just guessing)
So any other clue?
I'm running Ubuntu 10.04, Apache2, and StackOverflow :D
Thank you all.
EDIT: As suggested by p_strand, I've added a line
AuthzSVNAccessFile /etc/apache2/svn-policy-file
in dav_svn.conf config
Now, if I try http://localhost/svn/test it remains the same, and if I try http://localhost/svn I get a 403 Forbidden
luso@bender:/media/ssd/svn$ ls -lart

This is probably your problem - while the repository directories are accessible to the www-data user, their parent directory /media/ssd isn't. It and all its parent directories up the tree need at least world-execute permission (rwx--x--x or 711). The www-data user doesn't need to be allowed to read these directories but it does need to be able to descend into them (which is what the execute bit means for a directory).
In case anyone gets here with similar issue, here is my resolution:
I had file "/var/svn/format" owned by root, and despite all permissions set (777), apache did not want to read file owned by root.
Just a simple chown command fixed the issue.
