[Proftpd-user] Still not clear about <limit> vs. UNIX file permissions

[Stewart D. <st...@qs...>]

List members,
I am still unclear about the relationship between unix file permissions 
and <limit> directives. No matter how I arrange the <limit> commands, 
they seem to be either ignored or over-ruled by the underlying unix file 
   permissions relative to the user and group of the person logging in. 
In short I don't understand what the point/function of <limit> commands 
are, if they are simply trumped by unix in each case.

For example I have tried this:

<Anonymous /home/ftp>
AnonRequirePassword		on
User				Test1
Group				Test1

<Directory *>
	<Limit WRITE>
	DenyALL
	</Limit>
</Directory>
</Anonymous>

The file permissions are as follows: (note the user/group doesn't match 
Test1)

drwxr-xr-x    6 upload   ftp          4096 Aug 31 10:35 Inbox
drwxr-xr-x    6 upload   ftp          4096 Aug 31 00:02 Outbox


Still I am able to login and write anything I want to this directory and 
all sub folders. Clearly it is the r-x of the unix permissions that 
allows this. I repeat. What is the value of declaring limits if unix 
always wins?

Thank you in advance for helping me understand.
