Hello,
I got the same error and to answer your questions :
1. With local administrator first and domain administrator with ocspackager...
When I run the package with an account with admin rights -> no problem in logs;
When a non-admin run it -> ERROR *** AGENT => Failed to write Prolog Frequency <Error code 5 = Access is denied. >
2. No user is declared in ocsinventory.ini
Is this error blocking something? I tried to sync computer with OCS inventory -> OK; OCS inventory with GLPI -> OK.
It seems not blocking sync but I want to be sure it won't be a problem if I deploy it to the whole company.
Thanks in advance for your answer.
