Problem in documentation on samba an ldap part

[donzr]

Hi, I want to report this issue that I just found on the Ubuntu Server's documentation (here is the link :https://help.ubuntu.com/11.10/serverguide/C/samba-ldap.html) as you can see it is for the samba and ldap section and the problem comes when we need to add the samba indexes to the config tree through the samba_indices.ldif file.
So, here is the problem:

The problem comes because olcDatabase={1}hdb,cn=config already has an attirbute olcDbIndex: uidNumber eq which causes the problem, so I fixed it by erasing uid number olcDbIndex: uidNumber eq

I added this indexes to the tree :
dn: olcDatabase={1}hdb,cn=config
changetype: modify
add: olcDbIndex
may be this attribute is already added**************olcDbIndex: uidNumber eq****************
olcDbIndex: gidNumber eq
olcDbIndex: loginShell eq
olcDbIndex: uid eq,pres,sub
olcDbIndex: memberUid eq,pres,sub
olcDbIndex: uniqueMember eq,pres
olcDbIndex: sambaSID eq
olcDbIndex: sambaPrimaryGroupSID eq
olcDbIndex: sambaGroupType eq
olcDbIndex: sambaSIDList eq
olcDbIndex: sambaDomainName eq
olcDbIndex: default sub

so, in my opinion, a note explaining the situation would help.
Thanks guys, I appreciate your time.
