We're running FMS 22.214.171.1242 and from time to time the external authentication stops working. The only way to solve it I've found is restarting the server.
The Filemaker server is running on a Mac Mini server 10.10.5 which is connected to the Open Directory of a 10.11 XServe.
The Filemaker authentication still works. When I check the Directory Utility of the machine running FMS, it is connected and I can see the accounts of the Open Directory. But the FMS seems not to be getting the OD info.
Does anyone have a clue on what to do to solve this. We have had this problem since some month.
