Can you please explain the logic?

Also if I miss the blank between DNS and username then it doesn't work.

Code:
wgp-fap-109:~ # ./srk.sh
DNS=cn=afpuser,o=company
DNS=cn=afpuser,o=company
pwd
wgp-fap-109:~ # cat srk.sh
#!/bin/bash

var='DNS=cn=afpuser,o=company : pwd'

service=${var%% *}
user=${var#* = }
pass=${user#* : }
user=${user% : *}

echo $service
echo $user
echo $pass

NAME

       Net::DNS::Mailbox - DNS mailbox representation

SYNOPSIS

	   use Net::DNS::Mailbox;

	   $mailbox = new Net::DNS::Mailbox('user@example.com');
	   $address = $mailbox->address;

DESCRIPTION

       The Net::DNS::Mailbox module implements a subclass of DNS domain name objects representing the DNS coded form of RFC822 mailbox address.

METHODS

   new
	   $mailbox = new Net::DNS::Mailbox('John.Doe@example.com');
	   $mailbox = new Net::DNS::Mailbox('John Doe <j.doe@example.com>');

       Creates a mailbox object which represents the DNS domain encoded form of the mail address specified by the character string argument.

       The argument string consists of printable characters from the 7-bit ASCII repertoire.

   address
	   $address = $mailbox->address;

       Returns a character string containing the RFC822 mailbox address corresponding to the encoded domain name representation described in
       RFC1035 section 8.

DOMAIN NAME COMPRESSION AND CANONICALISATION

       The Net::DNS::Mailbox1035 and Net::DNS::Mailbox2535 subclass packages implement RFC1035 domain name compression and RFC2535
       canonicalisation.
