squid3 + winbind из samba3 + NTLMSSP

Привет, коллеги.

Кто подскажет?
Есть работающая связка squid3 + winbind (из samba 3.0.24-2)

/etc/squid3/squid.conf

auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp
auth_param ntlm children 30
auth_param ntlm keep_alive on

auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic
auth_param basic children 30
auth_param basic realm Squid proxy-caching web server
auth_param basic credentialsttl 2 hours

external_acl_type NT_global_group protocol=2.5 ttl=30 children=20 %LOGIN /home/peter/bin/wbinfo_group.sh

wbinfo_group.sh - мой

#!/bin/sh

while read from_squid; do
user=`echo $from_squid | awk '{print $1}'`
group=`echo $from_squid | sed -e "s/^[^ ]*//" -e "s/^ //"`
g_sid=`wbinfo -n "$group" | awk '{print $1}'`
g_gid=`wbinfo -Y "$g_sid"`
wbinfo -r "$user" | grep -qs "^$g_gid\$" 2>/dev/null && echo "OK" || echo "ERR"
done

Тот perl'овый, который идет со сквидом не воспринимает группы с пробелом.

В /var/log/squid3/access.log летит вот такое

1171450639.179 1 cleaning-12.mcbfa.local TCP_DENIED/407 2546 GET http://moscowmap.ru/maps_pit.asp? - NONE/- text/html

т.е. с пустым полем user
нормальная запись выглядит так

В /var/log/squid3/cache.log летит вот такое
