I have changed permissions to most-permissible and still no luck. Any directory under the samba share that is not on the physical primary partition seems to fail. Here are the permissions as provided in the shell: ls -lad /remote/samba_share drwxrwxr-x 13 me users 0 May 29 15:49 /remote/samba_share ls -la /remote/samba_share drwxr-xr-x 4 me users 0 May 8 14:19 /remote/samba_share/local_dir drwxr-xr-x 16 me users 0 May 14 19:49 /remote/samba_share/second_drive drwxrwxrwx 12 me users 0 May 30 09:42 /remote/samba_share/ext_raid NOTE: I started this as a question on stackoverflow, because of the number of other possible causes, but led to this bug report. http://stackoverflow.com/questions/10818770/php-is-readable-fails-on-readable-samba-directory Test script: --------------- if (is_readable('/remote/samba_share' )){ echo "share ok\n"; } else { echo "share BAD\n"; } if (is_readable('/remote/samba_share/local_dir' )){ echo "local ok\n"; } else { echo "local BAD\n"; } if (is_readable('/remote/samba_share/second_drive' )){ echo "second ok\n"; } else { echo "second BAD\n"; } if (is_readable('/remote/samba_share/ext_raid' )){ echo "raid ok\n"; } else { echo "raid BAD\n"; } Expected result: ---------------- share ok local ok second ok raid ok Actual result: -------------- share ok local ok second BAD raid BAD ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62199&edit=1
