Below the solution. Resolved By "Alon Bar-Lev" <alonbl(a)redhat.com>
1. install ovirt-engine-extension-aaa-ldap, it is available in
ovirt-3.5-snapshots repository.
2. create /etc/ovirt-engine/extensions.d/din.intranet-authz.properties
ovirt.engine.extension.name = din-intranet-authz
ovirt.engine.extension.bindings.method = jbossmodule
ovirt.engine.extension.binding.jbossmodule.module =
org.ovirt.engine-extensions.aaa.ldap
ovirt.engine.extension.binding.jbossmodule.class =
org.ovirt.engineextensions.aaa.ldap.AuthzExtension
ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Authz
config.profile.file.1 = /etc/ovirt-engine/aaa/din.intranet.properties
3. create /etc/ovirt-engine/extensions.d/din.intranet-authn.properties
ovirt.engine.extension.name = din-intranet-authn
ovirt.engine.extension.bindings.method = jbossmodule
ovirt.engine.extension.binding.jbossmodule.module =
org.ovirt.engine-extensions.aaa.ldap
ovirt.engine.extension.binding.jbossmodule.class =
org.ovirt.engineextensions.aaa.ldap.AuthnExtension
ovirt.engine.extension.provides = org.ovirt.engine.api.extensions.aaa.Authn
ovirt.engine.aaa.authn.profile.name = din.intranet
ovirt.engine.aaa.authn.authz.plugin = din-intranet-authz
config.profile.file.1 = /etc/ovirt-engine/aaa/din.intranet.properties
4. create /etc/ovirt-engine/aaa/din.intranet.properties
include = <ipa.properties>
vars.user = uid=admin,cn=users,cn=accounts,dc=din,dc=intranet
vars.password = 123456
vars.server = ipa1.din.intranet
pool.default.serverset.single.server = ${global:vars.server}
pool.default.auth.simple.bindDN = ${global:vars.user}
pool.default.auth.simple.password = ${global:vars.password}
5. restart engine.
Thanks a lot Alon.

Just a couple of addtions=2C please hash the password with SSHA =28I really=

I tried putting an =7BSSHA=7D encoded password in =22vars=2Epassword =3D=22=

But I still have to test that as our second replica is down at the moment=

Also can we get rid of the internal admin or better just disable
internal authenticationt without problems=3F As we have ipa we don=27t want=

Thanks a lot Alon.
Thanks for this, saved me some time!
Just a couple of addtions, please hash the password with SSHA (I really hate
plain text admin passwords...)
I tried putting an {SSHA} encoded password in " vars.password =" , but it
fails to authenticate while plain text works fine.
I am unsure I understand.
using hash to store password hint at server side makes sense.
but using hash to store password at client side does not makes sens, this means that if I
get the server database I can authenticate to any user without knowing his password.
Also, please note that the user you specify within configuration should not have any
special privilege but to query public objects within ldap.
For people with multiple ipa replica's I you guess you need to
use:
Round robin configuration: vars.server1 = ipa1.din.intranet
vars.server2 = ipa2.din.intranet pool.default.serverset.type =
round-robin
pool.default.serverset.round-robin.1.server = ${global:vars.server1}
pool.default.serverset.round-robin.2.server = ${global:vars.server2}
instead of
vars.server = ipa1.din.intranet pool.default.serverset.single.server =
${global:vars.server}
But I still have to test that as our second replica is down at the moment.
Correct, there are multiple policies for you to choose from.
Also can we get rid of the internal admin or better just disable
internal
authenticationt without problems? As we have ipa we don't want local login
enabled, but in emergency situations we might need to turn it on quickly.
Yes, you can disable the internal by creating
/etc/ovirt-engine/engine.conf.d/50-disable-internal.conf
---
ENGINE_EXTENSION_ENABLED_builtin-authn-internal = false

Hmmm.... we have a bug in this case... will fix, so let's just disable the authz for
now.

ENGINE_EXTENSION_ENABLED_internal = false

I don't like storing plain text in textfiles, so I try to avoid it. Even
if it is a read only user there are no "public" objects that I like to
expose to anyone. I can query groups, group members, e-mail addresses,
krbPasswordExpiration, krbLastPwdChange etc. with this user.
So that's why I try to have the bind user password hashed in the
properties file.
as I wrote above, storing hash instead of password does not enhance security.
it is the same as if you just set the user's password to the hash.

Ah yes, silly me. You are absolutely <br>
right. It has been such a long <br>
habit... But it does help when people intercept the traffic. Does the <=

ldap plugin send it hashed to the ldap server? <br>
<br>
I think FreeIPA supports salted sha512 but I'm not entirely sure. <br>
<br>
You'll probably say that I need to enable TLS, but there have been many

weaknesses in ssl and MITM issues. So more is always better in a <br>
security perspective. <br>

Ah yes, silly me. You are absolutely
right. It has been such a long
habit... But it does help when people intercept the traffic.
No it is not... exactly the opposite... if the hash is sent it is actually weaker than
password, as it has lower diversity.
If you wish you can enable digest-MD5 and use SASL, but still you must store the plain
password at client side.
Does the
ldap plugin send it hashed to the ldap server?
I think FreeIPA supports salted sha512 but I'm not entirely sure.
You'll probably say that I need to enable TLS, but there have been many
weaknesses in ssl and MITM issues. So more is always better in a
security perspective.
Using plain protocol will always be weaker than using TLS, even if you use digest-MD5,
kerberos or any other challenge-response mechanism.
As the password must be kept at client side no mater what protocol you use, using TLS and
simple bind is the minimum you can have.
I believe that TLS + simple bind is sufficient for most usages for a user that has no
special access to information.
From my experience enabling SASL does have its issues, but you may
want to check it out if you do not trust TLS, but even if you use SASL, better to use it
over TLS.
