[Samba] samba3.0.23d group permissions not working

Dear all,

I have samba3.0.23d running on FreeBSD 6.1. It is running with "security = ADS" and has been functioning correctly from about 3.0.14 to 3.0.22.

Since I upgraded to 3.0.23(a|b|c|d) group permissions are not honoured by Samba. For example:

drwxrwx---  107 setup     domain admins  3072 Nov 15 19:25 install

The user setup is a windows admin user; this user can access this folder without any problems. Any users in the "Domain Admins" group CANNOT access this folder. When trying to do this from windows they are presented with a password screen. This is the same for all group permissions unless the group is in question is the user's primary group. If I explicitly add ACL user permissions to the folder then those users can access it. This doesn't work if I can group ACLs.

This has screwed up all sorts of stuff as all group based access is broken.

I am not seeing any winbind errors; winbind seems to enumerate the groups fine, eg

[root at yankee /data]# id cmurdoch
uid=15003(cmurdoch) gid=15000(domain users) groups=15000(domain users), 15009(group policy creator owners), 15006(enterprise admins), 15007(domain admins), 15008(schema admins), 15017(emlibrary users), 15030(sophos console administrators), 15033(sophosadministrator), 15035(pcarch), 15038(BUILTIN\administrators)

But cmurdoch then won't be able to access folders with any of his group permissions set.

Global section of smb.conf:
workgroup = BPR
netbios name = YANKEE
;hosts allow = 192.168.1
socket options = TCP_NODELAY
server string = Samba Server
security = ADS
encrypt passwords = yes
password server = *
client use spnego = yes
server signing = auto
map acl inherit = yes
;allow trusted domains = no
idmap uid = 15000-1000000
idmap gid = 15000-1000000
winbind use default domain = yes
winbind enum groups = yes
winbind enum users = yes
winbind nested groups = yes
template shell = /usr/local/bin/bash
use sendfile = yes
log file = /var/log/samba/log.%m
load printers = no
