And the log isn't much more forthcoming.

Looks like you have disallowed anonymous bind on your LDAP.
We are trying to estabilish anonymous bind to test the connection.

I would recommend to try to do a manual configuration, the documentation
is here:

 
https://github.com/oVirt/ovirt-engine-extension-aaa-ldap/blob/master/README#L17

Then in your /etc/ovirt-engine/aaa/profile1.properties add following
line:

pool.default.auth.type = simple

Then test the configuration using ovirt-engine-extensions-tool.
If it's OK just restart ovirt-engine and all should be fine.
