@Chetan_Savade: Thanks, but I was able to do what I needed to do via command-line. I prefer to use WinSCP, so I'm just trying to report this as a bug so it hopefully will be fixed in a future release. In the meantime, I can just use command-line when I need to do this process again.

Hi,

Why don't you use Filezilla FTP client to connect FTP server

Re: Only the first FTP post login command is ran!

1. Here is an example using command-line and sending the user and password via non-interactive literals. I issue the command literal USER <username> followed by literal PASS <password> and I am then logged in. 
C:\Users\cld09\Desktop>ftp ftp.entsupport.symantec.com

Re: Only the first FTP post login command is ran!

Please post a complete session log file showing that.

Re: Only the first FTP post login command is ran!

Okay, but I tested two other (non-interactive) post-login commands. It looks as if only the first post-login command is ran and any additional commands are ignored.

Re: Only the first FTP post login command is ran!

You cannot use interactive commands in Post login commands. What USER is.

Only the first FTP post login command is ran!

I am running WinSCP Version 5.1.3 (Build 2881) on Windows 7. When I connect to an FTP site (via command line), I first need to supply a username and password for my organization's firewall. Once I supply the username and password, I am connected to the FTP site, but need to login to the FTP site. So, as you can see in the command-line example below, I type the command USER, supply the username and password, and I have logged in successfully. To do this using WinSCP, I would supply ftp.entsupport.symantec.com (the FTP site I'm trying to connect to) as the host name, but for username and password I would supply my organization's firewall user and password. Of course, I need to specify the username and password for the FTP site itself. When doing this via command line, I had to type the command USER. In WinSCP I would go to Environment > FTP and specify the following two post login commands: 
USER iosupport

PASS *****

The problem is that WinSCP only sends the first command (USER iosupport) and not the second command (PASS *****). So, because of this, WinSCP cannot be used because the password is never sent. By the way, it looks as if WinSCP sends these post login commands as literals, so just typing USER iosupport <password> won't work. However, literals also work on command line, but again the problem here is that WinSCP doesn't even attempt to pass the second command.

Command line example: 
C:\Users\cld09>ftp ftp.entsupport.symantec.com

Connected to exftpp.symantec.com.
