Fedora directory users - Mar 2007 - admin-server error and cloning incapacity

Hi,

I an running FDS 1.0.2 and 1.0.4 and I''ve got the same problem on both 
boxes : the admin-server error logs shows this :

[Wed Mar 14 14:06:19 2007] [notice] [client x.x.x.x] 
admserv_host_ip_check: ap_get_remote_host could not resolve x.x.x.x
[Wed Mar 14 14:06:19 2007] [error] [client x.x.x.x] client denied by 
server configuration: /opt/fedora-ds/Operation

I can access to the console interface and directory server''sinterface.
I don''t know how to fix that issue. Moreover, I think since this time,
I
can''t clone anymore directory server configuration....

Any idea what could be causing this error ?

Thanks,

Greg
