Samba user doesn't recognize group membership - FTP does

Version: 8.1-RELEASE

I have a samba share set up (version 3.4) and I created the username mtest.
Code:
sudo smbldap-useradd -a mtest

sudo smbldap-passwd mtest (set password)

Then I add mtest into the group 'prime' and 'pm'
Code:
 sudo smbldap-groupmod -m mtest prime
Code:
 sudo smbldap-groupmod -m mtest pm

Code:
$ id mtest
uid=1044(mtest) gid=503(prime) groups=503(prime),1004(pm)

Looks good to me. To test, I set up permissions and ownership on the folder TEST1:

Code:
sudo chown -R user:prime TEST1
sudo chmod -R 770 TEST1

here's my ls -l:
Code:
drwxrwx---    4 user        prime                 512 Nov 18 14:49 TEST1

So when I go to a windows machine and log in to the samba share (mapped network drive) as the user mtest, I can't even access the folder TEST1. This also happens if I change the folder over to the 'pm' group.
Code:
sudo chown -R user:pm TEST1

However, if I connect to the server via SFTP as mtest, I can access and create subdirectories in the folder TEST1, whether the folder is owned by the group prime or pm.

Why is it that samba doesn't recognize group membership, yet SFTP does? Let me know if you need more info and Ill be glad to supply.
 
I would like to also add that the username 'mtest' does show up if I use either command
Code:
pw groupshow prime

or

pw groupshow pm

I can also ssh into the server as mtest and access the folder TEST1.

I also found this interesting:
Code:
$ wbinfo -r mtest
Could not get groups for user mtest
Code:
$ wbinfo -t
checking the trust secret via RPC calls failed
error code was NT_STATUS_CANT_ACCESS_DOMAIN_INFO (0xc00000da)
Could not check secret

It seems that
Code:
hosts allow = 192.168.0. 127.
blocks all network requests, except 192.168.0.127. There should be only ipv4 network ID, ex. 192.168.0.0.

Code:
[files]
  comment = Files
  path = /home/
  writable = yes
  guest ok = no

I've never used ldap so far, but for me few lines are missing here.

Code:
[files]
  comment = Files
  path = /home/
  writable = yes
  guest ok = no
  [B]write list = @prime[/B]  //allowing group "prime" to read & write.
  [B]browsable = yes[/B]

Code:
browsable = yes
is missing from all of your shares. Without that you can't browse a share.
 
Thanks for the suggestions. I know this is going to sound dumb, but I gotta restart the SMB service when I make those changes right?

As I remember Samba reloads configuration every 60 seconds automatically, but you can do that immediately with [cmd=]service samba reload[/cmd] command.
 
I read up on the hosts allow at : http://www.samba.org/samba/docs/using_samba/ch06.html

From what I gathered, the
Code:
hosts allow = 192.168.0. 127.
would allow anyone on our network of 192.168.0.*, plus the local machine 127.0.0.1. I guess it's odd that whoever just left it at 127. Think it would be ok to fill out the rest of that 127 with .0.0.1?

I added the lines you suggested, but still no go.

Something I found odd was that I tried just recreating the user (mtest). Before my output would be like:
Code:
$ id mtest
uid=1044(mtest) gid=503(prime) groups=503(prime),1004(pm)

But now its like this:

Code:
$ id mtest
uid=1046(mtest) gid=513(Domain Users) groups=513(Domain Users),503(prime),1004(pm)

I did not create the user any differently. I even copied and pasted the commands from my first post to recreate the user.
 
Another odd thing is, even with the
Code:
browsable = yes
missing from the shares, people have been using it just fine (read and write). My smb.conf file is in /usr/local/etc, is that the normal path? Am I even looking at the right smb.conf?

Yes, /usr/local/etc/smb.conf is the default Samba configuration file. I've just looked into Samba docs: http://www.samba.org/samba/docs/man/manpages-3/smb.conf.5.html#BROWSEABLE. It seems that [CMD="browsable"]= yes[/CMD] is default setting for every share.
 
Oh, ok that makes sense about it being the default. I hate this server. I've never had a box do so many odd things.
