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

Thu Nov 22 23:22:05 GMT 2007

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

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

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.

id412113

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?
