Apache 2.0 with Subversion authenticate against Active Dir..

Hi *,

running the subversion module on Apache 2.0 I want the user to
authenticate with his/her user name and password managed by a Microsoft
Windows 2000 Domain Controller. It should be possible to do this using
the LDAP protocol. The configuration looks like this

<Location /svn/>
DAV svn
SVNParentPath H:\SVN
AuthType Basic
AuthName "Subversion repositories"
AuthLDAPURL
"ldap://itssrv1:389/dc=solution,dc=de?samAccountName?sub?(objectCategory=person)(objectClass=user)"
AuthLDAPBindDN "CN=soladmin@solution.de"
AuthLDAPBindPassword "drowssap"
require group cn=svnusers,dc=Builtin,dc=solution,dc=de
</Location>

There is an administrative account for "soladmin" and the
Subversion-Users are members of the group "svnusers". However, the
authorization failes. Can anybody help me?

BTW: Using a Java-program "ldapbrowser" it is possible to browse the
tree. The configuration is the follwing:

Host: itssrv1
Port: 389
Version: 2 (it's the version number of the LDAP-Protocol)
Base-DN: DC=solution, DC=de
SSL: no
Anonymous Bind: no
User DN: soladmin.RemoveThis@solution.de
append Base-DN: no
password: drowssap

Thanks in advance.
