Correcting user information in TDX is very simple- all you need to do is access the Admin application, go to the Users section, lookup the user in question and fix what needs to be fixed. Detailed instructions are below.
1 - Open the admin app
From the ticketing system you can click the Applications button in the top left and you should see the Admin option first- if you don't then you need to be setup as an admin in the system, please reach out to a TDX administrator to get that set up for you.
2 - Navigate to the Users & Roles Section to Find the User
On the left menu bar towards the bottom you should see the Users & Roles section
Once clicked this will open up a sub-menu with the different Users & Roles options, click on the Users option to pull up the Users list where you can search for the user you need to fix. Searching by last name is usually the best way since there can be different first names based on the user's preference.
3 - Edit the User
Once you click on a user's name you'll see that the user page pops up. From here you can edit or add anything that is missing. The biggest culprits will be missing SAM Account Number/Login username which should be in the Organizational ID field, Employee IDs which should be in the Alternate ID field, and the username (email) itself (which you can see from the search page but is not easy to see from the user page for some reason). The Org ID and Alternate ID can be changed from the main page, and the username can be changed by clicking Actions > Change username
Once you've made the necessary changes, click the Save button and you're all done!
