NAME

       RT::Extension::MergeUsers - Merges two users into the same effective user

RT VERSION

       Works with RT 4.0, 4.2, 4.4, 5.0.

DESCRIPTION

       This RT extension adds a "Merge Users" box to the User Administration page, which allows
       you to merge the user you are currently viewing with another user on your RT instance.

       It also adds "MergeInto" and "UnMerge" functions to the RT::User class, which allow you to
       programmatically accomplish the same thing from your code.

       It also provides a version of CanonicalizeEmailAddress, which means that all e-mail sent
       from secondary users is displayed as coming from the primary user.

INSTALLATION

       Be sure to also read "UPGRADING" if you are upgrading.

       "perl Makefile.PL"
       "make"
       "make install"
           May need root permissions

       Edit your /opt/rt5/etc/RT_SiteConfig.pm
           If you are using RT 4.2 or greater, add this line:

               Plugin('RT::Extension::MergeUsers');

           For RT 4.0, add this line:

               Set(@Plugins, qw(RT::Extension::MergeUsers));

           or add "RT::Extension::MergeUsers" to your existing @Plugins line.

       Clear your mason cache
               rm -rf /opt/rt5/var/mason_data/obj

       Restart your webserver

UPGRADING

       If you are upgrading from 0.03_01 or earlier, you must run bin/rt-update-merged-users.
       This script will create MergedUsers Attributes so RT can know when you're looking at a
       user that other users have been merged into. If you don't run this script, you'll have
       issues unmerging users. It can be safely run multiple times, it will only create
       Attributes as needed.

UTILITIES

   rt-clean-merged-users
       When a user with another user merged into it is shredded, the attributes on that user are
       also shredded, but the merged user will remain, along with attributes that may point to
       the now missing user id. This script cleans up attributes if the merged-into user record
       is now gone. These users will then be converted back to regular unmerged users.

   rt-merge-users
       A command-line tool to merge one user into another

CAVEATS

   RT::Shredder and Merged Users
       Merging a user effectively makes it impossible to load the merged user directly.
       Attempting to access the old user resolves to the merged-into user.  Because of this,
       MergeUsers has some extra code to help RT::Shredder clean up these merged records to avoid
       leaving merged user records in the DB while removing the user they were merged into.

       When running RT::Shredder on a user record with other users merged into it, the merged
       users are Unmerged before the initial user record is shredded.  There are two options to
       handle these newly unmerged users:

       1.  Re-run your shredder command with the same or similar options. The unmerged user
           records will now be accessible and, depending on your shredder options, they will
           likely be shredded on the second run. If you have multiple layers of merged users, you
           may need to run shredder multiple times.

       2.  MergeUsers will log the unmerged users at the "info" level so you can pull the user
           ids from the log and shred them manually. This is most likely to be useful if you are
           shredding one specific user (and all merged accounts).
