Should I report this on the bugzilla ?
You can, but I beleive this is not bug, but some misconfiguration, many times I've tried completelly simillar setup and it worked.
Btw.. did you used 'ovirt-engine-extension-aaa-ldap-setup'? If not you can install it. $ yum install ovirt-engine-extension-aaa-ldap-setup
Then just run: $ ovirt-engine-extension-aaa-ldap-setup
And follow the steps. This tool handle for you all perms and typos issues, which could be introduces by manually creating those properties files.
Yes this is actually the tool I used first, then I modified manually as on the documentation. The problem in this approach is the fact you need a .profile file to be able to set up a TLS connection between the LDAP and the engine. But this file is generated after the interactive setup. But the interactive setup doesn't allow you to setup things properly as the TLS isn't set up... So I had to setup things with "insecure" mode and then edit it manually...
