InnerAttributes not escaped when transmitted to outter

Hey all, I'm using PEAP/Mschapv2 with Windows machines. I need the user-name of the inner-tunnel when the authentication ends to assign the vlan id. So I put in eap.conf / peap { ... use_tunneled_reply = yes ... }, and now I can have the User-name of the inner-tunnel with %{reply:User-Name}. But it seems it has not been escaped... My User-Name "DOMAIN/testx" becomes => "DOMAIN estxx" And if I try DOMAIN/user it works nicely... ++[eap] returns ok +- entering group post-auth {...} ++[exec] returns noop expand: %{request:User-Name} -> ANKAMA\testx expand: %{reply:User-Name} -> ANKAMA estxx How can I escape this ?
