Subject: [Users] OpenLDAP Simple Authentication in Ovirt Engine
Hi,
I am currently testing Ovirt 3.1 standalone on Fedora 17.
Until now, I could only use the default user admin@internal.
Our Directory at the University is OpenLDAP. We use it for
authentication
WITHOUT Kerberos : Simple authentication.
I wonder how to use this backend to authenticate users and manage
groups
in Ovirt.
Has anyone already set this up ?
How to configure Ovirt to use Simple Authentication (No Kerberos).
Cheers,

http://lists.ovirt.org/mailman/listinfo/users Hi,
This is a response from an older thread from Yair Zaslavsky:
" there is no code allowing to add simple-authentication domains
to
Manage-Domains.
In the past we did have the ability to do that, but there are
several
problematic issues."
Best regards, Hi,
correct-me if I am wrong but this wiki page (
http://www.ovirt.org/DomainInfrastructure ) states clearly :
1. Authenticating Active Directory, IPA and RHDS using either
     simple or gssapi authentication
     2. Querying the directory using the LDAP protocol
     3. Auto deducing the LDAP provider type
     4. Easily adding new LDAP provider types
     5. Easily adding new query types
So what ? We supported simple authentication in the past, but it is
no longer
supported, that's why you can't set that using the manage domains
utility.
It may work well in some providers (in the past we supported that
for active directory, so I guess it would work there). I don't think
we removed SIMPLE from the engine, we just don't
recommend
using it, since it doesn't encrypt user/password on the network (it
is
sometime useful for debugging). We indeed didn't remove the engine
code. We just blocked it from the utility.
Once you have a configured oVirt domain, you can set the
LDAPSecurityAuthentication configuration parameter (in the
vdc_options table), to use simple, by putting a value of:
domain1:SIMPLE,domain2:GSSAPI,domain3:SIMPLE and etc....
but, if you want to add a new domain with it then you would need to
add it manually (can give a detailed explanation on how, if
relevant). Yes, I would like to know how to add directly a domain
which is not GSSAPI controlled.
The vdc_options table is a table containing the configuration values of the engine. Among those, there are directory-related configuration values:

engine=# select * from vdc_options where option_name in ('DomainName','LdapServers','LDAPSecurityAuthentication','LDAPProviderTypes','AdUserName','AdUserPassword');
 option_id |        option_name         |                  option_value                   | version
-----------+----------------------------+-------------------------------------------------+---------
         9 | AdUserName                 | domain1:user1,domain2:user2                     | general
        10 | AdUserPassword             | domain1:password1,domain2:password2             | general
       114 | LdapServers                | deomain1:ldap_server_address1,domain2:ldap_server_address2 | general
        64 | DomainName                 | domain1,domain2                                 | general
       112 | LDAPSecurityAuthentication | domain1:GSSAPI,domain2:SIMPLE                   | general
       115 | LDAPProviderTypes          | domain1:activeDirectory,domain2:ipa             | general

AdUserName is the user that will be used to query the directory.
AdUserPassword is the password that will be used to query the directory.
LdapServers - the LDAP server that will be used (only one is allowed in this configuration. This configuration is optional. If empty, we will check the DNS for LDAP SRV records for the relevant domain).
DomainName - the names of the domains
LDAPSecurityAuthentication - SIMPLE/GSSAPI
LDAPProviderTypes - the provider type (activeDirectory/ipa/rhds/itds)

All the entries above are per-domain, in the format domain1:value1, domain2:value2 and etc....

If manually adding a GSSAPI domain, you also need to supply a krb5.conf file, and put it in the ENGINE_ETC path. If adding a SIMPLE domain that isn't neccesary.

We haven't worked with simple domain for a while now, so hopefully it will work for you as expected.

Let me know if you have further questions.

...
By default we work GSSAPI (I think the config option is empty by
default which is equivalent to working GSSAPI).
If/When we would need to support that again it shouldn't be a major
effort to add the code... the testing with the different providers
will be the hard part.
Oved
We also don't auto deduce the LDAP provider type anymore, as
changes in the providers caused some issues with it.
I'll edit the wiki accordingly (btw, I remember removing it from
the wiki... so it is weird that it is still there...).
