Problem with authorization when using client 1.7.5

Hi,

we recently upgraded our SVN server to V1.7.5 (from 1.4). We migrated
the exact configuration. We use individual repos served by Apache 2.2.

Since the upgrade, we cannot check out the ROOT (/) of any repository
which has non-public read access (see below) with clients version 1.7.X,
we always get the error:

Error: Not authorized to open root of edit operation

What is interesting, is that older clients (e.g. 1.6.9) work fine
against the same repo.

Apache logs the following errors:

[Mon Jun 11 10:46:14 2012] [info] [client 192.168.0.38] Access granted:

The apache config for this repo looks like this:

<Location /Projects/Test/jh>

DAV svn

SVNIndexXSLT "/svnindex.xsl"

SVNPath /svn/Projects/Test/jh
AuthzSVNAccessFile /svn/Projects/Test/jh/svn-acl
AuthType Basic
AuthName "SVN /Projects/Test/jh"

AuthBasicProvider ldap
AuthLDAPURL ldap://thor/dc=sea-gmbh,dc=com
AuthzLDAPAuthoritative Off

Satisfy Any
Require valid-user

</Location>

and the svn-acl is:

[/]
jh=rw
*=

Any idea what might go wrong here? Should I file an issue?

Best regards,
        Jörg
