Bengt Rodehav commented on CAMEL-3309:
--------------------------------------

We use Serv-U in production running on Windows 2003 Server. However, our ftp 
server (Serv-U) is currently not used by our own software (using Camel). We run 
a hosting setup for our customer. When our customer's partners send or receive 
files to/from our customer then they are clients to Serv-U. When our customer 
needs to send or receive files to its partners, then our software is used as a 
client to the partners' servers. This is done using ftp, ftps or sftp (and 
Camel) depending on partner.

I honestly don't know what ftp servers the partners use. I know that at least 
one runs on z/OS. I will try to find that out but not everyone in the finance 
business wants to expose what internal software they use. I did check one of 
their servers (which we communicate with using sftp) using a GUI based sftp 
client. I could then see that the home directory was not referred to as "/" and 
that we did not have access to the intermediate folders leading down to the 
home directory. This was one of the reasons I created this JIRA ticket since 
stepwise changing of directory will not work.

> In Camel 2.5, the logic for changing directory for ftp/ftps/sftp has changed 
> in order to fix the problems discussed in the following thread:
>   
> http://camel.465427.n5.nabble.com/How-to-change-directory-while-using-sftp-component-td2806817.html#a2807611
> In Camel 2.5 changing of the remote directory is now done in a stepwise 
> manner. This is a strategy not fit for production since it assumes that the 
> logged in ftp/ftps/sftp user has access to all intermediate directories all 
> the way down to its home directory. This is rarely the case.
> Also, when testing ftp/sftp on Serv-U, a Windows based ftp/ftps/sftp server, 
> it turns out that it reports the current directory in a "Windows way", e g 
> /C:/temp/servu/user/sample/file2sftp. The topmost folder is not "/" but 
> "/C:". This also breaks the new stepwise way of changing directory since it 
> always tries to change to "/" if an absolute path is used.
> I propose to introduce a configuration property to enable/disable stepwise 
> changing of directories where disabling it should be the default. I will 
> upload a patch shortly.
