[Samba] Problem when "valid users" is used

Thu Sep 30 02:20:48 MDT 2010

I add "loglevel 768" into slapd.conf and I have this in my sulog file :

Sep 30 09:37:19 xxxx slapd[23852]: conn=2110 op=47 SRCH 
base="dc=company,dc=com" scope=2 deref=0 
filter="(&(objectClass=posixGroup)(uniqueMember=cn=developpeurs,ou=groups,dc=company,dc=com))"
Sep 30 09:37:19 xxxx slapd[23852]: conn=2110 op=47 SRCH attr=gidNumber
Sep 30 09:37:19 xxxx slapd[23852]: conn=2110 op=47 SEARCH RESULT tag=101 
err=0 nentries=0 text=

I don't understand why Developpeurs group is not find here (nentries=0).

# ldapsearch -x -b 'ou=groups,dc=company,dc=com' cn=Developpeurs

return :

cn=Developpeurs,ou=Groups,dc=company,dc=com
objectClass: top
objectClass: posixGroup
objectClass: sambaGroupMapping
cn: Developpeurs
gidNumber: 1005
sambaSID: S-1-5-21-1003513250-1319205365-1235820382-1015
sambaGroupType: 2
displayName: Developpeurs
