[rt-users] Multiple email addresses for a single login name

[Kyle Balling]

OK, after hours and hours of pouring over the code in 
/opt/rt3/lib/RT/Interface/Email.pm I have a solution.

Now if there is a user, for example Joe, who has two or three or 10 
email addresses, RT will make it work. For example if Joe uses, 
joe at domain1.com and joe at domain2.com he will be able to create tickets by 
email and RT will not create two users or give an error. So here is what 
I changed.

(From Email.pm  with changes commented ) ---------------

# {{{ Create User

sub CreateUser {
    my ($Username, $Address, $Name, $ErrorsTo, $entity) = @_;
    my $NewUser = RT::User->new($RT::SystemUser);

     
 ##### I inserted this part to give me normal user names instead of the 
entire email address as the username
        my ($name, $domain) = split(/@/, $Address);
#####


       my ($Val, $Message) =
      $NewUser->Create(Name => $name,     ##### used to be ($Username || 
$Address),
                       EmailAddress => $Address,
                       RealName => $Name,
                       Password => undef,
                       Privileged => 0,
                       Comments => 'Autocreated on ticket submission'
                      );

     unless ($Val) {

        # Deal with the race condition of two account creations at once
        #
 
##### the function LoadByName doesn't work for some reason.
#        if ($Username) {
#            $NewUser->LoadByName($Username);
#        }
#####
#This seems to work and updates the user's email address to the most 
recently used one
                if ($name){
                        $NewUser->Load($name);
                        $NewUser->SetEmailAddress($Address)
                        }
#####

        unless ($NewUser->Id) {
            $NewUser->LoadByEmail($Address);
        }

      unless ($NewUser->Id) {
            MailError( To => $ErrorsTo,
                       Subject => "User could not be created",
                       Explanation => "User creation failed in 
mailgateway: $Mes
sage",
                       MIMEObj => $entity,
                       LogLevel => 'crit'
                     );
        }
    }


    my $CurrentUser = RT::CurrentUser->new();

        $CurrentUser->LoadByEmail($Address);

    unless ($CurrentUser->id) {
            $RT::Logger->warning("Couldn't load user '$Address'.".  
"giving up")
;
                MailError( To => $ErrorsTo,
                           Subject => "User could not be loaded",
                           Explanation => "User  '$Address' could not be 
loaded
in the mail gateway",
                           MIMEObj => $entity,
                           LogLevel => 'crit'
                     );
    }

    return $CurrentUser;
}
# }}}


That seems to work and is a good work around if a single username has to 
be mantained for multiple emails.
Please tell me if there are any errors.
