Description (partial)

Symptom:
When trying to configure ISE 2.6p3 with VanDyke SFTP server, either from CLI or GUI, we are receiving the below debug output.
#debug transfer 7
#debug copy 7

We can see here that ISE is trying to send "//" in the filepath. This is causing the communication between ISE and VanDyke SFTP server to fail.
