I'm on Mac OS X 10.7.2 with a serious permissions issue that affects most items in my Documents folder, which now require my password for modifications like renaming. The concerned files and folders also seem hidden from Spotlight and therefore do not show up in searches. Both issues are seriously problematic for everyday use.
This is what
ls -l gives me for folders:
drwxr-xr-x 109 fr staff 3706 Nov 22 14:43 Notes drwxr-xr-x+ 16 fr staff 544 Nov 22 14:51 Bibliography
Notes folder is showing fine in searches and allows for password-free renaming, the
Bibliography folder does not. My understanding is that the
+ sign indicates what is wrong here.
Edit: tentative solution below, by removing all ACLs.
