Hi, I have previously configured LDAP 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. With this one 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.
