FTP Advanced Proxy Settings Restrictions

The following restrictions are applied:

CA CSM does not support actual user IDs and passwords within the <FIRECMD> element.
CA CSM supports concatenating proxy user IDs with FTP user IDs (anonymous), and concatenating proxy passwords with FTP passwords (ID for the CA Support Online website). However, concatenating a proxy user ID and proxy password, or anonymous with the ID for the CA Support Online website is not supported.
For example, the following sample is supported:
```
<FIRECMD>USER;@REMOTE_USER;</FIRECMD>
<FIRECMD>PW;@REMOTE_PW;</FIRECMD>
```
The following sample is not supported:
```
<FIRECMD>USER;PW;</FIRECMD>
<FIRECMD>REMOTE_USER;REMOTE_PW;</FIRECMD>
```
In this case, put the user ID and password on separate FIRECMD elements, for example:
```
<FIRECMD>USER;</FIRECMD>
<FIRECMD>PW;</FIRECMD>
<FIRECMD>REMOTE_USER;</FIRECMD>
<FIRECMD>REMOTE_PW;</FIRECMD>
```
