[Samba] Solaris 9 Winbind "ls -l" hangs - group mapping

OS Solaris 5.9 (9) Generic_122300-13 (clean build)

nscd daemon has been disabled and is not running

No NIS or NISPLUS

 

Samba Version 3.0.26a

Complied using the following options --with-acl-support -with-winbind
-with-pam

 

smbd, nmbd & winbind daemons are all started

 

[global]

      workgroup = MTCB2

      security = domain

 

      log level = 3

      log file = /usr/local/samba/var/samba.log.%U

      max log size = 20000

      ldap ssl = no

 

      wins server = 172.26.175.1

      dns proxy = yes

      name resolve order = wins bcast host

 

      idmap uid = 10000-20000

      idmap gid = 1000-2000

 

      winbind enum users = yes

      winbind enum groups = yes

      path = /data

      valid users = @"MTCB2\domain users"

      browseable = yes

      read only = No

 

Requirement: Use winbind to authenticate XP clients.

 

Domain Windows 2003 (Domain functional level 2000 native)

 

nsswitch.conf

passwd: files winbind

group: files winbind

 

I have complied configured and installed Samba on a test network. I have
joined the samba server as a domain member on to the Windows 2003 domain
and I can list all the users and groups in the domain using  wbinfo -u
and groups using wbinfo -g. I can also list all the users using "getent
passwd" but when I run the command "getent group" I only get one
of the
domain groups returned.

 

I can logon to an XP client access the shares on the Samba server and
create files, folders etc. I can list these file on the UNIX server
using "ls" but if I try and use "ls -l" the command just
hangs. Also
"smbstatus" hands if there are any files open.

 

If I remove the winbind from the group entry in the nsswitch.conf file
then I can list the contents of the folders, obviously the group names
do not appear but the domain usernames do. I can then also get a from
"smbstatus" again all group name a shown as there mapped ID

 

Authentication is very quick, there just seems to be a problem with
group mapping.

 

 

I followed the instructions on this web page to install and configure.

Other tests carried out

 

smbclient -L hostname

nmblookup -B ip_addr __SAMBA__

nmblookup -N ip_addre "*"

nmlookup -M DOMAIN

 

The gid range does not clash with existing groups and I cannot see any
errors in the log files.

 

All give normal output.

 

Any ideas?

[Samba] Solaris 9 Winbind "ls -l" hangs - group mapping

I removed winbind from group entry in /etc/nsswitch.conf, otherwise ssh
session would timeout and lost connection. In this way, Samba still
works. Samba still can use domain groups and domain users to grant
access. Only 'getent group domain_group" doesn't work.

Cheers

[Samba] Solaris 9 Winbind "ls -l" hangs - group mapping

Thanks for your reply, I have got a stage further with this problem and
discovered it is a time out issue.

"getent group" only returns the first group "Domain Admins"
the next
group in the list is "Domain Users" this group has over 573 members
(all
users).

As this is a test domain, I proved this by deleting the majority of
users and "getent groups" then returns all the group names. I can
further prove this by listing some of the other groups by name i.e.

getent group "Domain\design"

This works fine and returns all the users.

I recreated the users (scripted!!) and getent groups fails again. But I
have found that by deleting just 40 members all groups are listed.

Not sure where to go from here. I think this must be a Solaris issue, a
timeout somewhere? A limitation of the number of users in a group?

I think I can get round this issue by forcing the files to be created on
the samba share as one particular group. But I would rather solve the
problem!

I have found similar reference on other sites, but no solution.

This could be a problem with ldap client, but the client is not
configured or running on my Solaris install.

If it could be how do I configure ldap client on Solaris?

Kevan Gibbings

Solaris...

Review your hostname definition carefully.  Ensure that the FQDN is 
defined and that it maps to the correct ipaddress.  Test it with 
nslookup.  Solaris can get very cranky if there is something wrong with 
this.

Also review the ldap configuration.  It can be the ldap configuration 
that causes the delay.  Test an ldap query against ADS manually.

Cheers,

[Samba] Solaris 9 Winbind "ls -l" hangs - group mapping

Found the answer to the problem, I think!

When listing the groups from the Solaris server "getent group" I
believe
there is a maximum length of string that "getent" can handle.

I have proved this by configuring a new test domain with its netbios
name only 2 charters long (old name one was 5). I then recreated all the
users (scripted!!) and "getent group" can now return a full list of
groups.

This means that it is not the number of users it is the length of string
returned.

I have taken this one step further and created an extra 500 users and
again "getent group" fails to list the "Domain Users" group.

We have a contract with Sun so I will report as a bug, I have checked
the latest patches but no joy.

Regards
Kevan Gibbings
