To keep things simple, I customized the auth-source variable to debug
and also the tramp-default-method to ftp. Even though I will want to
make ssh default, my concern at this point is to get access to web
server. I saved the customization.

With SSH to local hosts, I am presently successfully using
.authinfo. The reason for ssh showing up in the output is that I was
uncertain how to set the method for tramp to use, and to took most
conservative choice for the trial run. 

In my ~/authinfo I have the line:

  machine Host.com port ftp login Benutzer password Geheim

Here is the answer to my question, which the info or man documents did
not answer. This defines the FTP method for the tramp sesson, and I
assume this overrides any tramp default method I may have set.

Running the address returns the request for password, and so .authinfo
apparently not used. The only thing in the *Messages* buffer is the
report that I've created customization setup. Only when I do RET in lieu
of providing a password, do I get a message. 

  1. Custom settings cannot be saved. Maybe you started Emacs with
     -q. 

     This indeed is what I'm doing. However, in my tramp init file
     I have the line (setq auth-source-debug `trivia).

  2. Tramp Default Method: ftp. State: EDITED, shown value does not take
     effect until you set or save it. 

Nothing here about the tramp session. 

I put (setq tramp-default-method "ftp") into my tramp init file and run
again. After the third RET in liew of password, I get a dump:

  (ftp-error #("FTP Error: USER request failed: 530 Login incorrect."

  call-interactively(find-file nil nil)
  read-string("Password for ussir03@uss-irex.info: " nil t nil)
  read-passwd("Password for ussir03@uss-irex.info: ")

It seems it finds .authinfo file but can't read it. 

   $ ls -la | grep authinfo
   -rw-r--r--  1 haines haines   1169 Jan 16 11:55 .authinfo

The password has a couple "#" characters in it, so I put it into
quotation marks, but it didn't help.
