[Samba] question about groups

[Adam Williams]

I created a group in ldap:

dn: cn=web,ou=Group,dc=mdah,dc=state,dc=ms,dc=us
objectClass: posixGroup
objectClass: top
cn: web
userPassword:: xxxxxxxxxx
memberUid: akazery
memberUid: dhglover
memberUid: cgoodwin
memberUid: mglover
memberUid: jlongmire
memberUid: awilliam
gidNumber: 1010

and ran:

net groupmap add rid=3021 ntgroup="Website" unixgroup=web type=d

and in smb.conf had:

[web]
        path = /var/www/sites
        public = no
        writeable = yes
        create mode = 0664
        directory mode = 0775
        force group = web
        valid users = @"ADMIN\Website"
        csc policy = disable
        profile acls = yes
        nt acl support = no


but my users still couldn't access the share.  However, when I changed 
the line to valid users = @"ADMIN\Web" then they could access the share 
fine.  shouldn't the group name ADMIN\Website worked fine since I did 
the net groupmap add command?
