I have OCS NG and GLPI set up and working fine idependently of each other on the same host. For a while GLPI was sccuessfully importing computers from OCS NG, but now GLPI shows there are new computers to import but doesn't do anything when requested to import them.

How do I find what is going on? Are there any log files or debug modes I can turn on? Documentation on the interaction of these pieces of software is pretty sparse.
