[SOLVED] Unable to save to samba mount having group-write priv

mfoley · 03-23-2016, 05:28 PM

I have Slackware64 14.1 and it has been running samba 4.x for over 6 months without problem. I just updated the OS and now have Samba 4.1.23 running (not sure what the previous version was -- it's gone). Now, on samba mapped folders to Windows, users cannot write to directories if they are not the owner, even if the folder has group rw and the samba account is the same group. For example:

Code:

$ ls -l /srv/tomcat/webapps/ohprs/downloads/minutes
drwxrwsr-x 2 mfoley ohprs 4096 2016-02-22 09:54 Retirement\ Board/

The folder is owned by mfoley, but is group writable to members of the ohprs group.

Members of ohprs are:

ohprs:x:301:mfoley,tomcat,daemon,apache

and also:

ohprso:x:1001:301:OHPRS Web FTP User:/srv/tomcat/webapps/ohprs/downloads:/bin/bash
ohprs:x:1002:301:HPRS Batch:/home/ohprs:/bin/bash
guest:x:1001:301:Samba guest account:/dev/null:/bin/false

Notice that guest and ohprso are the same UID.

Relevant smb.conf is:

Code:

[global]

netbios name = WEBSERVER
   workgroup = WORKGROUP
   server string = HPRS webserver Samba Server

   security = user
   map to guest = Bad User

   hosts allow = 192.168.0. 127.

guest account = guest

   passdb backend = tdbsam

   socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

   dns proxy = no

[website]
path = /srv/tomcat/webapps/ohprs
public = yes
guest ok = yes
guest only = yes
writeable = yes
browseable= yes
printable = no
create mask = 0660
directory mask = 0771

So, why could group members of ohprs (301) write to this folder before, but not now? How can I fix thix?

Never mind. Duh! I now remember I had this problem last time I installed Slackware 14.1. The out-of-the-box samba has this problem, but the updates fix it. I didn't restart samba after updating. When I did, problem gone!
