Fedora directory users - Jan 2007 - Virtual Views entries only as leaves?

Hi all,
We''ve recently been migrating our data from an OpenLDAP server to FDS.
The data import went smoothly, very impressed.

However, I am currently experimenting with using a virtual view to
allow a flat directory structure to be displayed as a hierachical
view. Through experimentation I''ve only found it possible to add
virtual entries as leaves. Is it possible to have virtual entries in
an organizational unit that contains another organizational unit with
other virtual entries.

I''m sure that makes no sense so I''ve attempted to draw the
tree
stucture I''m trying to achieve. ou=view contains the virtual view and
ou=entries contains the actual entries.

dc=root
- ou=view
- - ou=group
- - - ou=subgroup
- - - - o=org1
- - - - o=org2
- - - o=org3
- ou=entries
- - o=org1
- - o=org2
- - o=org3

In the virtual view ou=group contains both ou=subgroup (with it''s own
virtual entries org1&2) and a virtual entry (org3) of its own. At the
moment I only seem able to get the deepest OU to display virtual
entries (ou=subgroup in this example).

Does anyone know if what I am trying is possible or are virtual
entries only able to be added at the deepest container?

You should be able to do that. Are you sure that the o=org3 entry 
doesn''t match the filter in ou=subgroup? Also, do all three entries 
ou=view, ou=group, ou=subgroup have the objectclass nsview?

Hi Pete,

Thanks for the reply, here is the LDIF of my test tree:

dn: dc=test
dc: test
objectClass: top
objectClass: dcobject

dn: ou=view,dc=test
objectClass: top
objectClass: organizationalunit
objectClass: nsview
ou: view

dn: ou=entries,dc=test
ou: entries
objectClass: top
objectClass: organizationalunit

dn: o=org1,ou=entries,dc=test
o: org1
objectClass: top
objectClass: organization

dn: o=org2,ou=entries,dc=test
o: org2
objectClass: top
objectClass: organization

dn: o=org3,ou=entries,dc=test
o: org3
objectClass: top
objectClass: organization

dn: ou=group,ou=view,dc=test
ou: group
objectClass: top
objectClass: organizationalunit
objectClass: nsview

dn: ou=subgroup,ou=group,ou=view,dc=test
ou: subgroup
objectClass: top
objectClass: organizationalunit
objectClass: nsview
nsViewFilter: (|(o=org1)(o=org2))


That works OK, however when I add an ''nsViewFilter: (o=org3)''
attribute to ou=group, org3 displays correctly as a virtual entry
under ou=group but ou=subgroup stops displaying org1 and org2 as
virtual entries.

Any ideas?

Thanks,
Ewen

Yes :)  You have misunderstood how views work a little. Each view with a 
filter restricts the descendant entries that may exist in the hierarchy, 
so the higher view filters should be general like o=finance, then the 
next level might be (o=Purchasing) with a peer (o=Sales), a third level 
under the latter might contain (o=USA Sales) and (o=Canada Sales). Each 
time you add a sub-view with a view filter it will remove those entries 
that match from the parent and begin displaying them in the sub-view. To 
get what you are after you would need to add something like (o=*) or 
(|((o=org1)(o=org2)(o=org3))) to the ou=group entry.

Yes! It works :) Big thanks for the help Pete.
