[Samba] winbind with ldap backend permissions

hi,

I set up a winbindd with a ldap backend, here is the relevant part of my
smb.conf:

idmap backend = ldap:ldap://mail.rhel.homelinux.com
ldap admin dn = cn=winbind,dc=example,dc=com
ldap suffix = dc=example,dc=com
ldap idmap suffix = ou=idmap

On the ldap server I set up the ou=idmap and also permissions for
cn=winbind to write into the ou=idmap:

access to dn="(.),ou=idmap,dc=example,dc=com"
	by dn="cn=winbind,dc=example,dc=com"
	by * read

when trying a "getent passwd" on the client I get the following error
messages on the ldap-server:

Oct  6 13:02:49 mail slapd[21955]: conn=2 op=22 SEARCH RESULT tag=101
err=0 textOct  6 13:02:49 mail slapd[21955]: conn=2 op=23 MOD

Oct  6 13:02:49 mail slapd[21955]: conn=2 op=24 RESULT tag=105 err=50

base="ou=idmap,dc=example,dc=com" scope=2
filter="(&(objectClass=sambaIdmapEntry)(sambaSID=S-1-5-32-547))"

so, seems that winbind have no write access on the PARENT! if I give him
write access on dc=example,dc=com everything works just fine and the
sid/uid/gib-mapping works wonderful. but why is winbind needing access
on the parent and not just on the ou-container where the id-mapping
happens, ou=idmap?

can anybody explain that to me?!

thanks and greetings,
thorsten
