Re: [Samba] User's home folders
If you have samba/ldap running and the users home directories are listed in ldap. The homes should be mounted on logon. Other way you have [homes] and [user_data] described in your smb.conf and [netlogon]. In netlogon there should be a batch-file to mount your shares at logon.

Perhaps you should mount the home directories on the server via cifs. I use the following script lines (as part of a longer script): Login="rw,file_mode=0644,dir_mode=0755,username=$User,password=$Passwort,noserverino" mount -t cifs -o $Login //$Rechner/$1 /mnt/$Rechner/$Verz By the way (and as mentioned some days ago): you don't need something like "freeradius" for this job.

I configured pam on my laptop and i can login using the credentials of some users of the ldap tree but it doesn't recognize and it doesn't mount neither the home directory nor the public directory. But logging with the same users, locally on the server, it recognizes and it use the home. I miss the configuration on the client to mount the samba share and home directories. Next thing i'll want will be that a client windows can authenticate against freeradius-ldap on the lan and can browse the samba share and his home also. step by step!

[Samba] Login Attempt Resets Password in smbpasswd
Hello,
I am running Samba 3.4.7 on Ubuntu 10.04 amd64. Due to legacy support, I am
using a smbpasswd file (chmod 600) instead of the newer tdbsam database. It is
also worth noting that this server also has LDAP authentication enabled (for
SSH access). Clients access Samba from both Windows 7 and Windows XP. The
smb.conf file is as follows:
[global]
workgroup = HOME
printcap name = /etc/printcap
load printers = no
printing = lprng
log file = /var/log/samba/%m.log
max log size = 0
security = user
encrypt passwords = true
passdb backend = smbpasswd
smb passwd file = /etc/samba/smbpasswd
unix password sync = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *New*password* %n\n *Retype*new*password* %n\n
*passwd:*all*authentication*tokens*updated*successfully*
pam password change = yes
obey pam restrictions = yes
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
local master = no
os level = 65
domain master = no
preferred master = no
name resolve order = wins bcast host lmhosts
wins server = xxx.xxx.xxx.xxx
dns proxy = no
idmap uid = 16777216-33554431
idmap gid = 16777216-33554431
template shell = /bin/false
winbind use default domain = no
[MyShare]
path = /mnt/MyShare
browseable = yes
public = yes
guest ok = yes
writable = yes
printable = no
create mode = 0664
directory mode = 0775
veto oplock files = /*mgc*/
force create mode = 0660
force directory mode = 0660
Samba is not a PDC, however the Windows accounts on client machines have the
same credentials as are stored in smbpasswd, so the share is automatically
authenticated. I have observed that if a user is required to enter their
password, e.g. their Windows password is not the same as in smbpasswd, then
their password in smbpasswd gets reset. For example, before attempting to
connect, user1's entry in smbpasswd looks like this (password hashes randomized
in example below):
user1:111: f0faf5d8955e92206354485d29a1b15e : e580c2260de48ababdd67d6ed063a641
:[UX ]:LCT-4E985F55:
After the user attempts to connect, and enters the wrong credentials,
user1:111: : e580c2260de48ababdd67d6ed063a641
:[UX ]:LCT-4E985F55:
Thus if the user then tries a second time with the correct password, they are
unable to login. If the correct password is supplied the first time, then no
change is made to smbpasswd. Sometimes the password gets changed to X...
even after a successful login. When this error occurs, nothing is logged in
/var/log or /var/log/samba. An strace of the parent smbd process reveals only
the following:
gettimeofday({1335971419, 254991}, NULL) = 0
select(27, [6 24 25 26], [], NULL, {, 0}) = 1 (in [24], left {9993,
133747})
gettimeofday({1335971425, 122816}, NULL) = 0
accept(24, {sa_family=AF_INET, sin_port=htons(61726),
sin_addr=inet_addr("192.168.1.20")}, [16]) = 28
clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD,
child_tidptr=0x7f07d9ead9f0) = 4371
close(28) = 0
gettimeofday({1335971425, 133599}, NULL) = 0
Do you have any ideas on why the smbpasswd file is being changed, and how to
correct this behavior so the smbpasswd file is not changed?
Thanks,
Andrew

Re: [Samba] SMB2 write performace slower than SMB1 in 10Gb network

Then I change "max protocol" to "SMB2" in smb.conf to enable SMB2, other configs in smb.conf are not changed, restart samba, reconnect in Windows 2008, use Iometer to run test again, I got 470 MB/s write performance and 505 MB/s read performance. It's quite good that read performance bursts with SMB2, but write performace droped by 140 MB/s, I run this write test serveral times again, write performance indeed droped a lot, so is it normal that SMB2 write performance is slower than SMB1? No, this is not normal. Maybe you want to enable async I/O. Depending on the platform, plain aio might work with aio write size = 1 It might be a good idea to also enable vfs objects = aio_fork With latest Samba Jeremy Allison has also added the aio_pthread module, but that is not yet in released code. You can get it from the latest v3-6-test branch in our git repository. With best regards, Volker Lendecke Tested SMB2 write peformance again under 10Gb network with AIO enabled, I set aio write size = 1 and got 332.17 MB/s output, which is slower than previous 470 MB/s (AIO disabled), enable aio_fork vfs object, test result is almost the same. In my opinion, SMB2 write should be faster than SMB1 even when AIO is disabled, isn't it?
