apache2 fails ldap auth on vmdk>qcow2 kvm vm

[m.ardito]

Hi, i converted two disks (sda, sdb) of a working vmware vm (ubuntu server + lamp).
Everything worked since first boot, except a virtualhost (the main one on that machine) which authenticates users against win2003 AD, which from the logs fails authenticating users

command line ldapsearch testing works both on the kvm vm and on the proxmox host (debian+pve), and i can read averything on the AD...

any hint of what could make mod_authnz_ldap apache2 module fail, having just converted vmdk to qcow2?

vmdk were copied from real disk with vmware-vdiskmanager (-t 0)
copied vmdks were then converted (-O qcow2) to .qcow2 format

i post here just to be sure nothing at pve level could block or interfere with this..., as i am a pve beginner: could be something in the bridged network?

pveversion -v output:
----------------------
pve-manager: 1.5-7 (pve-manager/1.5/4660)

------------------

we can't really figure out what could be wrong...
Any hint would be greatly appreciated...

UPDATE:
solved reading this: http://www.issociate.de/board/post/152598/OpenLDAP_to_Active_Directory_

basically windows2003 server was answering differently, to this (i supposed cloned from the vmdks) vm

changing the ldap auth comand from
AuthLDAPURL
ldap://corp.ad.company.com/dc=ad,dc=company,dc=com?sAMAccoun tName?sub?(objec
tClass=user)

that works on my vmware but not on my kvm (cloned from vmware)

in

AuthLDAPURL
ldap://corp.ad.company.com/cn=users,dc=ad,dc=company,dc=com? sAMAccountName?s
ub?(objectClass=user)

solved the problem, and now this setup works on both...

but why ?
