Thanks for your reply!
Firstly, as for the SSH connection, I need the ticket to have a controled
name, and not a randomized one. That problem is fixed by my patch.
As for the FTP problem, the thing is that when I logout from the FTP
connection, the system does not delete the ticket file, and so I have
hundreds of tickets there.
When I login/logout in SSH, the ticket gets deleted; but in the FTP it
doesn't.. That's the problem... :)
