Hello everyone. I have previously configured LDAP connexion though ovirt-engine-extension-aaa-ldap-setup. The only working configuration was IBM Security Directory Server (the IBM Security Directory Server RFC-2307 Schema doesn't work), ladps and anonymous search user. But the LDAP server I’m testing is OpenLDAP and not IBM. Indeed with IBM the search and login are working fine when I test them with ovirt-engine-extensions-tool aaa. But when I try to add a LDAP User in the User Administration Panel I get this Error message : "Error while executing action AddUser : Internal Engine Error". None of the solutions I've found on previous threads seems to works. Does someone have an idea please ? Please find the logs attached. Thank you beforehand.
