rlm_winbind group membership check

Hi.

I need to authenticate wifi users via PEAP(mschap) with group checking
against windows active directory. We have several domains in transitive
relations. Basic authentication via winbind works fine. But since the
groups may be in different domains, I must check group membership with
domain prefix. And I can not set up rlm_winbind to work correctly. Could
you help me, please.

root at chtpzfreeradius:/opt/sbin# cat /opt/etc/raddb/users | grep -v "#"

DEFAULT Winbind-Group == "CHTPZ0\\wifi_chtpz"
        Service-Type = Framed-User,
        Tunnel-Type = VLAN,
        Tunnel-Medium-Type = IEEE-802,
        Tunnel-Private-Group-ID := "165"

DEFAULT Auth-Type := Reject
        Reply-Message = "Groups do not match"

root at chtpzfreeradius:/opt/sbin# cat /opt/etc/raddb/mods-enabled/winbind |
grep -v "#"

winbind {
        winbind_username = "%{%{Stripped-User-Name}:-%{User-Name}}"
        group {
                group_search_username = "%{%{Stripped-User-Name}:-%{
User-Name}}"
                group_add_domain = no
        }
        pool {
                start = ${thread[pool].start_servers}
                min = ${thread[pool].min_spare_servers}
                max = ${thread[pool].max_servers}
                spare = ${thread[pool].max_spare_servers}
                uses = 0
                retry_delay = 30
                lifetime = 86400
                cleanup_interval = 300
                idle_timeout = 600
        }
}


Output of radiusd -Xx shows, that module strips domain part of group name.
