Client Mac refused access to related DB

[gregm1]

I've got a user who gets a "permission denied" message when trying to open a DB, the error refers to a related DB of the one being opened. I can access his account from my Mac, and from a fresh user account on his Mac, suggesting there is something amiss in his home folder.

So I tried deleting any permissions and cache files I could find relating to FMP. I also tried deleting his login keychain.

I've run out of ideas, does anyone have any suggestions?

Thanks.

I'm still troubleshooting this, I'd rather not recreate his OS X account. There must be a file somewhere that is causing this. Can anyone help?
