No go with extract, but using a RE helped. Thanks to exim-users for
helping here.

Can you please try this new, simplified authenticator?

plain:
  driver = plaintext
  public_name = PLAIN
  client_send = "<; ${if !eq{$tls_cipher}{}{\
                     ^${extract{1}{:}\
		        {${sg{\
                          ${lookup{$host}nwildlsearch{CONFDIR/passwd.client}{$value}fail}\
			  }\
			  {\\N[\\^]\\N}\
			  {^^}\
			 }}\
		       }\
		     ^${sg{\
		        ${sg{\
		          ${lookup{$host}nwildlsearch{CONFDIR/passwd.client}{$value}fail}\
			  }\
			  {\\N[\\^]\\N}\
			  {^^}\
			 }\
			}\
		        {\\N([^:]+:)(.*)\\N}{\\$2}\
		       }\
		   }fail}"


Cc'ing pkg-exim4-devel to solicit comments from the other guys there.
