Hi, I'm trying to use the directory services provided by the ovirt-engine-extension-aaa-ldap, and I can get it to successfully login when I run the tests in the setup script, but when I login via the GUI, it gives me: unexpected error was encountered during validation processing: javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated' and fails login. It looks a bit like it is expecting to already be joined to the domain, so I tried doing that manually via realmd and sssd. It involved installing a lot of packages, such as kerberos and samba, which I am nervous about on an engine host. Anyway, once I was joined, it still gives me the same 'peer not authenticated' message. Does it need to be separately bound to the domain, i.e., do you need all the other stuff installed and running for it to work, or is the ovirt-engine-extension-aaa-ldap package all that is needed?

Anyway, I ran the ovirt-engine-extensions-tool --log-level=FINEST --log-file=/tmp/aaa.log aaa search --extension-name=domain-authz command suggested in an earlier post, and it only gave me one exception, which was: 2016-09-28 16:08:15 SEVERE Extension domain-authz could not be found 2016-09-28 16:08:15 FINE Exception: org.ovirt.engine.core.extensions.mgr.ConfigurationException: Extension domain-authz could not be found

Hi Ondra, Not really. aaa-ldap by default uses just simple bind, no gssapi. If you have any problems with certificate I would suggest you to check if you are using the correct one, correctly. More info for it can be found here: https://gerrit.ovirt.org/gitweb?p=ovirt-engine-extension-aaa-ldap.git;a=b... <https://gerrit.ovirt.org/gitweb?p=ovirt-engine-extension-aaa-ldap.git;a=b... I've run the following tests in that README you posted above, and all worked fine: ovirt-engine-extensions-tool aaa login-user --profile=mydomain.com <http://mydomain.com> --user-name=myuser ovirt-engine-extensions-tool aaa search --extension-name=mydomain.com-authz --entity=principal --entity-name=myuser LDAPTLS_REQCERT=never ldapsearch -ZZ -H ldap://ad.mydomain.com <http://ad.mydomain.com> -x -D "CN=myuser,CN=Users,DC=mydomain,DC=com" -W -b "dc=mydomain,dc=com" I thought I wouldn't need to import any certificate from AD - is that a requirement?

Do I need to set up Apache separately to use LDAP auth? The service principals exist in the krb5.keytab, but I don't if that is only if you are using SSO.

Hi Ondra, It's not, but you need to use insecure connection then (you need to have following line in /etc/ovirt-engine/aaa/domain.properties): pool.default.ssl.insecure = true I ended up generating a cert on one of the AD machines, copying it to the host, and then specified it in the setup process via ovirt-engine-extension-aaa-ldap-setup. It seems to create a .jks file. It still gave me the same 'peer not authenticated' so I checked the krb5.keytab and saw that there was no SPN for http, so I rejoined the domain and specified http as a service name via adcli, and then things worked. So double check that, and if it still won't work, the logs from ovirt-engine-extensions-tool would help, you can generate them as follows: $ ovirt-engine-extensions-tool --log-level=FINEST --log-file=/tmp/aaa.log aaa .... Do I need to set up Apache separately to use LDAP auth? The service principals exist in the krb5.keytab, but I don't if that is only if you are using SSO. Yes, that's only if you use SSO. If you use plain LDAP simple bind, you don't need anything related to kerberos. I think I was under the impression that you needed to join the domain in order to auth via AD. However, I've now seen one HOWTO that says that you just need the cert from AD to be able to auth securely though I'm not entirely clear whether that works for Apache. Is that correct - Kerberos, binding etc is not needed for the oVirt web interface to auth securely?

Hi Ondra, That is good to know that we don't need Kerberos - it complicates things a lot. I think the errors might be the options I'd selected during the setup. I was thrown a bit that it passed all the internal tests provided by the setup script, but failed on the web GUI. When I've seen 'unspecified GSS failure' and 'peer not authenticated' it's usually been due to Kerberos (though admittedly these are just generic errors). So I tried the Redhat guide for SSO at: https://access.redhat.com/documentation/en-US/Red_Hat_ Enterprise_Virtualization/3.6/html/Administration_Guide/ Configuring_LDAP_and_Kerberos_for_Single_Sign-on.html which uses Kerberos (in ovirt-sso.conf) I had to remove the symlink to the Apache config it says to create, as it results in internal server errors in Apache. It uses an SPN for Apache in the keytab. Now that you've confirmed that it can actually work without any need for the Kerberos stuff, I will start afresh from a clean setup and apply what I've learnt during this process. I'll try it out and let you know either way. Many thanks for all the help!

Hi Cam, this is OK, because we use user principal name(UPN)[1] for the 'username' field of the oVirt. So the result username will consist of UPN@authz-extension, so if your user's UPN is 'user@domain' and you will name your authz extension as 'domain', then the result username will be 'user@domain@domain'. The problem, that you can't get authorized is that you didn't assigned any permissions to your user.
