So what is your search user's DN ?
Is it:
dn="uid=ovirt,ou=People,dc=guest,dc=arnes,dc=si"
or
dn="uid=ovirt,ou=People,dc=arnes,dc=si"
Is it possible for you to try if different user works fine?
Because user with very similar DN works for me just OK.
At the time of posting I
did not notice the difference, thanks for the
spot. The correct DN is dn="uid=ovirt,ou=People,dc=arnes,dc=si".
Although that means that after upgrading to 3.5 the DN for the search
user is formatted differently when issuing an LDAP bind request.
In the end we noticed that the AAA part of oVirt was reworked in 3.5. We
deleted the old LDAP domain, that we manually inserted into the database
back in 3.2 days. Then we added LDAP as an authentication source as per
AAA instructions, which we found a bit vague. The README on github for
the AAA extension provided most of the information.
We also found that the format of external_id in the users table had been
changed from fdfc627c-d875-11e0-90f0-83df133b58cc to
fdfc627c-d87511e0-90f083df-133b58cc. So naturally users could not log
in. Instead additional users were created with this new format
external_id, a namespace with "dc=arnes,dc=si" and a new user_id.
We manually deleted the faux users, updated the external_id to the new
format and added a namespace entry for existing users.
That worked for us.
Kind regards, Mitja

We just upgaded oVirt from 3.4 to 3.5 and now users cannot
select the LDAP domain on the login screen. Only internal is
available.<br>
Our LDAP server is actually a 389DS instance and we are using
for authentication in oVirt without Kerberos. The existing
setup has worked since the days of 3.2.<br>
<br>
When we try to validate the domain, we get<br>
[root@brda ~]# engine-manage-domains validate<br>
Error: Cannot authenticate user ovirt to domain
guest.arnes.si, details: [LDAP: error code 32 - No Such
Object]; nested exception is
javax.naming.AuthenticationException: [LDAP: error code 32 -
No Such Object]<br>
Failure while testing domain guest.arnes.si. Details: Cannot
authenticate user to LDAP server.<br>
<br>
The LDAP log reports<br>
[18/Jun/2015:13:52:38 +0200] conn=3 op=0 BIND
dn="uid=ovirt,ou=Peopledc=guest,dc=arnes,dc=si" method=128
version=3<br>
As you can see there is a comma missing before
"dc=guest,dc=arnes,dc=si".<br>
<br>
Before the upgrade the bind DN was generated properly as<br>
[18/Jun/2015:12:42:45 +0200] conn=10219 op=0 BIND
dn="uid=ovirt,ou=People,dc=arnes,dc=si" method=128
version=3<br>
</font></blockquote>
<br>
So what is your search user's DN ?<br>
Is it:<br>
<font
size="-1">dn="uid=ovirt,ou=People,dc=guest,dc=arnes,dc=si"<br>
<br>
</font>or<br>
<br>
<font
size="-1">dn="uid=ovirt,ou=People,dc=arnes,dc=si"<br>
</font><br>
Is it possible for you to try if different user works fine?<br>
