[389-users] Re: anonymous queries on second suffix subtrees

Hi, Mark.

I did not expect a reply so soon!

When I query as "Directory Manager", I get the expected result.

I used the setup-ds.pl script to create the o=ethz,c=ch root suffx.

You should be using dscreate to create your instance, not setup-ds.pl

I used "dsconf backend create" to add the second suffix (o=psi,c=ch).

Did you add any entries to o=psi,c=ch ?

The subtrees are not properly connected to their respective root suffixes.

Could this problem be caused by missing entries in the two "root suffix" databases?

[root@el-dap ~]#
[root@el-dap ~]# /usr/bin/ldapsearch -H ldap://el-dap.ethz.ch/ -LLL -x -b 'o=psi,c=ch' '(ou=*)'
No such object (32)

So you did not initialize this suffix.  It is empty. 

When creating the backend you could have created the top database node entry by adding the "--create-suffix" option:

# dsconf slapd-YOUR_INSTANCE backend create --suffix o=psi,c=ch --create-suffix

Note - dscreate or dsconf do not add any aci's by default.  You have to add the aci's after initializing the database with some data.

[root@el-dap ~]#

Anonymous queries  on the two subtrees (ou=staff & ou=student) on root suffix (o=ethz,c=ch) 

return the expected result.

So searches on "ou=staff,o=ethz,c=ch" work?  But just searching on "o=ethz,c=ch" does not?  I'm getting confused because you keep changing which suffixes work or don't work.  First it was subtree's under o=psi,c=ch that didn't return any results, now it's different subtrees under o=ethz,c=ch

So if you are having issues with anything under "o=ethz,c=ch" then can you please run this search, and also clarify which subtrees work and don't work for anonymous searches under this suffix "o=ethz,c=ch":

# ldapsearch -D "cn=directory manager" -W -b "o=ethz,c=ch" aci=* aci

Thanks,
Mark

However, anonymous queries on the o=ethz,c=ch root suffix  also return no records.

with best regards,

David

Hello, 389ers.

I am migrating a whitepages server from OpenLDAP to 389-DS.

My instance has a root suffix with two subtrees (for staff and students).

Anonymous queries of the two root suffix subtrees return the expected results.

The instance also has a second suffix of "o=psi,c=ch" with three subtrees:

  ou=contacts,o=psi,c=ch
  ou=groups,o=psi,c=ch
  ou=users,o=psi,c=ch

Anonymous queries of the three "o=psi,c=ch" subtrees return NO records.

I have added ACIs for the three "o=psi,c=ch" subtrees and restarted the instance, but
anonymous queries of any of the three "o=psi,c=ch" subtrees STILL return no records.

Does anyone know how to allow anonymous queries?

First you don't need to restart the server when you add or change ACI's.  If you run the search as "cn=directory manager" does it return the results you expect?

Can you share all the ACI's you added to o=psi,c=ch subtrees?  Maybe gather all of them by using this search:

    # ldapsearch -D "cn=directory manager" -W -b "o=psi,c=ch" aci=* aci

Thanks,
Mark
