mod_vas_auth, Apache2, svn and AD groups

Hi,

I've setup mod_vas_auth to authenticate users and control access to Subversion repositories.

It succeeds when the AuthzSVNAccessFile file contains username (from the AD).
Does anyone knows if I can use the groups defined in the AD for control access?
(without duplicating them in the [groups] section of the AuthzSVNAccessFile )
Direct association of a AD group as a "SVN" group would be OK.
I mean:

[groups]
admin = userAD1 userAD2
one_group = this_group_comes_from_AD
another_group = that_group_comes_from_AD_too
[/]
* = r
@admin = rw
[/component1]
@one_group = rw
@another_group = r
*  =

is OK.

In case of: Apache 2.2.17, mod_auth_vas 3.6.7, subversion 1.7.5

Thanks in advance.
Laurent
