hi,

sorry, if i was too unprecise...

of course i'm working with acl's - otherwise i could hardly define those fine granulated rules

this is, what getfacls on /home/board gives:

~# getfacl /home/board

# file: home/board
# owner: root
# group: root
user::rwx
group::r-x
group:kids:r-x
mask::r-x
other::---
default:user::rwx
default:group::r-x
default:group:kids:r-x
default:mask::r-x
default:other::---

for some reasons, i don't want to work with "valid users" parameter, especially while working with scripts so this solution doesn't meet my expectations (as i already mentioned)

the problem is on the samba-side on unix-side the user "test_user" has access on /home/board, cause he's in group "kids", too

but samba just recognised group "users" for "test_user" because sambaPrimaryGroupSID maps to -> "users" so samba establishes a connection as user "testuser" / group "users", which fails because of my restrictive acl :/

so: is "valid users" my only chance?

no way of adding more GroupSIDs for samba-users in LDAP, that samba recognises, that user "test_user" is in more than one group ?

i mean: unix-side sees this...

~# id test_user
uid=596(test_user) gid=500(users) groups=500(users),522(kids)

thx for your help!!!

If you want to set multiple group acces, you must use ACL.
the valid user parameter in smb.conf force the right of directory but the
unix right is only for group user.

I am not shure if i got you right. You do not tell us the access rights of
the directory concerned.
If you'r primary uninx group is user and your dir. has:
drwx---rwx   root user board
they forbid your access. then you are not allowed to access, because group
rights match first and If you weren't user but world, then you would be
allowed. This has nothing to do with samba.
You might want to change the group to nogroup and work with acls (if ext3,
XFS and alike). Or if you have plenty of CPU-cycles to waste you might
work with "valid users" in smb.conf.
But i'm not a security or filesystem-expert and may be completely wrong.
Kind regards,

hi

i have a user
~# id test_user
uid=500,gid=500 (users),groups (users,kids)
as you can see, this user is in primary group "users" and also member of
group "kids"
if he tries to access /home/board via smb (Samba 3.0 + openldap) from a
windows client (XP), he fails, because his
sambaPrimaryGroupSID maps to -> "users"
and /home/board is not accessible for group "users" - just for "kids"
if i add
valid users = @kids

to /home/board - share, access is granted
isn't it possible in samba, that the user "test_user" gets an attribute
like
sambaSecondaryGroup in ldap ????
so that samba knows: "this user is in group users AND kids, so i have to
try connections to share /home/board as group users AND kids" ???
if i login locally to the samba PDC with a console as "test_user",
access to /home/board is granted, 'cause i'm member of "kids"
so there's no permission problem

please help me !!!
