I think I’ve misunderstood: I thought RT would treat identical info as one account, and LDAP lookup would take precedence.  How can I merge them so ldap lookup is always used, whether they submitted a ticket or not..?

I just ran into this myself when setting up our LDAP authentication.  Our problem was that the LDAP server did not actually have the email address stored, so the username created in RT was the email address.  I had to go in and manually change the usernames of all the accounts with email addresses in the username field.


What’s the value of ‘attr_match_list’ and ‘attr_map’ in your RT_SiteConfig.pm file?


Haven’t altered them from initial values, since it seemed to work at first…


# The list of RT attributes that uniquely identify a user

             'attr_match_list'      => [    'Name',



             # The mapping of RT attributes on to LDAP attributes

              'attr_map'             =>  {   'Name' => 'sAMAccountName',

                                                   'EmailAddress' => 'mail',

                                                   'Organization' => 'physicalDeliveryOfficeName',

                                                   'RealName' => 'cn',

                                                    'ExternalAuthId' => 'sAMAccountName',

                                                    'Gecos' => 'sAMAccountName',

                                                    'WorkPhone' => 'telephoneNumber',

                                                    'Address1' => 'streetAddress',

                                                    'City' => 'l',

                                                    'State' => 'st',

                                                    'Zip' => 'postalCode',

                                                    'Country' => 'co'


Our AD has email values defined.  A ticket submitter gets created with account name “name at address,” which of course also becomes that autocreated users’ email address.  The user then tries to log in, is checked on AD, their email address is the same, and it tells me “already a user with that email address.”  I want to tell it “yes, same person, if credentials match let them in!”
