Why openldap server? 
We do not support openldap at the moment.

Hi.

Further testing...
- Setup: one ldap server with added user to match ovirt searches
(while adding user in webadmin),
- Fedora 18, engine 3.2.1, openldap-server, simple authentication, no
firewalls,
- with packet inspection we can see ldap responding with requested
attributes
- still, there are errors in logs, see below, and no users are listed
in webadmin, engine fails to parse given attributes
- engine-manage-domains -action=validate returns "Invalid
credentials" even though binding is ok and ldap is replying with
data.
...
Can anyone point us to some documentation on this topic?
Is really AD the only good solution for user management?

Hi,

We're issuing a RootDSE query (once per LDAP domain configured).

We try to obtain from it the "defaultNamingContext" attribute.

If does not exist - we try to obtain ""NamingContexts"

We store the result at a "domainDn" (we have a data structure which
maps domains to information objects, one of the fields at the
information object is the DN of the domain) field, and we use it to
compose the full ldap URL we send the queries to.

Hi,

...
...

the system is trying to bind to ldap as:
...
...
bind request:
uid=cn=ovirt,cn=Users,cn=Accounts,dc=ourdomain,dc=si

...
...
...
I dont know how it knows dc=ourdomain,dc=si
...

It should be
...
...
bind request: cn=ovirt,ou=system,dc=ourdomain,dc=si" -b
"dc=arnes,dc=si

...
...
...
The same with the search: we have users in form as:
...

edupersonprincipalname=username@users.ourdomain.si
,dc=users,dc=ourdomain,dc=si

...
...

values in database:

is it possible to change the bind request that is sent to the

server? The default
uid=user,cn=Users,cn=Accounts,cn=our,cn=domain
is

not suitable.

can you please explain why / what you would like to change it

(not sure possible now, but there is work to make it more
