Freeradius ldap 802.1x

Hello i have to deploy Radius Server Whit LDAP 802.1x EAP-TLS and dynamic assign vlans.I have configured evretying execpt Dynamic Vlans . I have it working whit Ldap-Groups. If the PC is in the Group "Access_Vlan_1", it gives the Vlan1 but here comes my strugle.

The Windows Admins at my workplace dont want it working whit Ldap-Groups "We will forget to remote the Group or add "Access_Vlan_2" ", they want me to configure it whit Organizational Units(OU). Im unable to do that for the past few weeks. I cant find anything usful on this topic in freeradius website. My progress it that is finding the Computers DNs and in what OUs are they buti cant make the radius server to send radius atributes for Dynamic vlans.

Is it even possible to Dynamicly assign vlans whit the FreeRadius.

if you need any info from my config i will give it you . I just need to know is it possible to be done

Thank you in advance
