Well, secrets.el expects only strings as attributes. No conversion
foreseen. I don't know what auth-source.el does. If auth-source-search
also allows only strings (and symbol names) as attributes, then your
patch is right. Otherwise, if a :port attribute could also be an
integer, it shall be transformed to a string.

Ted?
