Hello everybody again!
We have managed to fix the problem, as we suspected the main problem was related to permissions on the execution of the binaries.
Our customer says that the partition on the machine is mounted as “noexec” as they do by default, so with this the OOD will not work correctly. By changing this mount option we have solved all the problems in the list, so now we have everything ready to work.
Once again thanks for your work and guidance Jeff.
Best regards!!!
