52 use warnings FATAL => 'all';
53 use base qw(RT::Shredder::Plugin::Base::Search);
57 RT::Shredder::Plugin::Users - search plugin for wiping users.
61 =head2 status - string
63 Status argument allow you to limit result set to C<disabled>,
64 C<enabled> or C<any> users.
65 B<< Default value is C<disabled>. >>
75 =head2 member_of - group identifier
77 Using this option users that are members of a particular group can
78 be selected for deletion. Identifier is name of user defined group
79 or id of a group, as well C<Privileged> or <unprivileged> can used
80 to select people from system groups.
82 =head2 replace_relations - user identifier
84 When you delete user there are could be minor links to him in RT DB.
85 This option allow you to replace this links with link to other user.
86 This links are Creator and LastUpdatedBy, but NOT any watcher roles,
87 this means that if user is watcher(Requestor, Owner,
88 Cc or AdminCc) of the ticket or queue then link would be deleted.
90 This argument could be user id or name.
92 =head2 no_tickets - boolean
94 If true then plugin looks for users who are not watchers (Owners,
95 Requestors, Ccs or AdminCcs) of any ticket.
97 Before RT 3.8.5, users who were watchers of deleted tickets B<will be deleted>
98 when this option was enabled. Decision has been made that it's not correct
99 and you should either shred these deleted tickets, change watchers or
100 explicitly delete user by name or email.
102 Note that found users still B<may have relations> with other objects,
103 for example via Creator or LastUpdatedBy fields, and you most probably
104 want to use C<replace_relations> option.
