Hi Michael,

thank you for your reply!

Yes, I have. Here is my TRAMP configuration:

(use-package tramp
  :config
    ---snip---
  (with-eval-after-load 'tramp
    (tramp-set-completion-function
     "ssh" (append (tramp-get-completion-function "ssh")
                   (mapcar (lambda (file) `(tramp-parse-sconfig ,file))
                           (directory-files
                            "~/.ssh/conf.d/"
                            'full directory-files-no-dot-files-regexp))))
    (tramp-set-completion-function
     "scp" (append (tramp-get-completion-function "scp")
                   (mapcar (lambda (file) `(tramp-parse-sconfig ,file))
                           (directory-files
                            "~/.ssh/conf.d/"
                            'full directory-files-no-dot-files-regexp)))))
    ---snip---
)

And I confirm this solution works for Icomplete but for some reasons it
doesn't work for Fido.
