[Samba] Winbind ldap samba 3 BDC getent passwd

[jean-marc pouchoulon]

Bonjour, 
	
	On Samba3 rpm, redhat 9


	I decided to do a strace on a 'getent passwd' command and have a
look.
      (Wbinfo -u and wbinfo -g works ) 

	I can see a time out.

connect(5, {sa_family=AF_UNIX,
path="/var/cache/samba/winbindd_privileged/pipe"}, 110) = 0
close(4)                                = 0
select(6, [5], NULL, NULL, {0, 0})      = 0 (Timeout)

	
ls -al /var/cache/samba/winbindd_privileged/pipe
srwxrwxrwx    1 root     root            0 oct 13 13:37
/var/cache/samba/winbindd_privileged/pipe

	What is the role of winbindd_privileged/pipe ? 
	I have a few problem with redhat 9 , unlinked with samba , does
winbind work on other site with RH 9 ?

	thanks


	Jean-Marc

Objet : RE : [Samba] Winbind ldap samba 3 BDC getent passwd answerdon't
retrieve domain users,can't login on the domain with users that are not
on /ect/passwd + typoerror ?


Hi ,
	I've just upgraded to the last samba rpm on a redhat 9 and I
have a new problem on winbind wbinfo -u and wbinfo -g this time don't
return user or group. getent passwd don't return the users but I think
this time it's a direct inheritance of the previous line. 
I can see in the log a 'lookupsid' with an unknow sid number 
I can suppose this sid number come from the install ( net getlocalsid
and netgetlocalsid DOMAIN give the good sid domain)

2 small other things:

If I use idmap backend = ldapsam:ldap://ip_address
I have 

[2003/10/02 08:01:40, 5] lib/module.c:smb_probe_module(113)
  Probing module 'ldapsam': Trying to load from
/usr/lib/samba/idmap/ldapsam.so [2003/10/02 08:01:40, 3]
lib/module.c:do_smb_load_module(46)
  Error loading module '/usr/lib/samba/idmap/ldapsam.so':

ce type [2003/10/02 08:01:40, 0] sam/idmap.c:idmap_init(136)
  idmap_init: could not load remote backend 'ldapsam'

With  idmap backend = ldap:ldap://ip_address winbind is able to start

Testparm give a warning:
Loaded services file OK.
'winbind separator = +' might cause problems with group membership.

	Hope this can help going further in the analyse.
