FMS itself does not cache anything, it hands the authentication request off to the OS who takes over.
AD integration in OSX has always been messy and a bit of a problem child. Perhaps there is some command line for the directory utility that can force a refresh?
I made some progress on this, for those that want to quickly kickstart an AD info update on their OS X Server bound to an AD domain.
Right now the caching time seems to default to 4 hours, which is way too long IMO. I'm trying to find a way to make that something like 5 minutes, which will make the process essentially automatic, but in the meantime you can kickstart it this way:
- Launch the Terminal app (from /Applications/Utilities/ or from the Dock if you keep it there)
- Copy and paste the following command to the Terminal and hit Return (you should just get another Terminal prompt)
After that, FileMaker will have updated user and group membership info.
I'll update this thread once I find a way to do this automatically. I hope to find the parameter that controls the cache timeout, but failing that, I'll be doing an AppleScript or shell script controlled by a launchdaemon that will just do a flushcache every few minutes.
