The server appear to be broken, if UID 81 exists, a search for 'UID
SEARCH UID 81' should return 81.  Do you know which server this is?

Because you are quoting the expression, not evaluating it.  Try:

(setq gnus-select-method `(nnimap "imap.bar.org"
                                  (nnimap-server-port 143)
                                  (nnimap-authenticator login)
                                  (nnimap-stream network)
                                  (nnimap-authinfo-file ,(expand-file-name
                                                          "~/.authinfo"))))

But I believe it would be more reliable to use the value you use now.
Nnimap invoke expand-file-name on the file name internally.

The manual has been fixed, there are now examples for nnimap too:

`nnimap-authinfo-file'
     A file containing credentials used to log in on servers.  The
     format is (almost) the same as the `ftp' `~/.netrc' file.  See the
     variable `nntp-authinfo-file' for exact syntax; also see *Note
     NNTP::.  An example of an .authinfo line for an IMAP server, is:

          machine students.uio.no login larsi password geheimnis port imap

     Note that it should be `port imap', or `port 143', if you use a
     `nnimap-stream' of `tls' or `ssl', even if the actual port number
     used is port 993 for secured imap.
