Issue/Introduction

Error Message :
Error code: ('13' - 'Permission denied')

Unix Agent in previous versions encounters 'Permission denied' errors during a Managed File Transfer (MFT).

This problem occurs when files are transferred that are located in a directory structure where different directories belong to different unprivileged users. 

Investigation

A problematic directory structure could look like this: 

drwxr-xr-x 15 userA prog 4096 Nov 24 11:25 /users/dev/userA 
drwx------ 3 userB users 4096 Nov 24 12:12 /users/dev/userA/userB 
drwxr-xr-x 2 userB users 4096 Nov 24 11:31 /users/dev/userA/userB/dir 
-rw-r--r-- 1 userB users 6 Nov 24 12:03 /users/dev/userA/userB/dir/text.txt

The Agent trace (TCP=9) will show errors similar to these:

==> the Agent fails at: 
MAIN-THREAD 20161012/080812.651 FileHandler get user 'uc4_barmer_test' home directory
MAIN-THREAD 20161012/080812.652 FT_Dir result 2003041 from FileHandler() call
