It would be useful to display the Organization (ldap attribute 'o') juste above the Organizational Unit (ldap attribute 'ou') in the "Employee Information" section of the users details in WebUI.
The GUI and CLI do not display all the attributes for the user entries, but it is possible to write plugins to extend the functionality. Please refer to Extending FreeIPA guide. Note that the guide applies to pre-4.5 plugins, and you will need to move your plugin Python code to ipaserver/plugins/ subdirectory instead of ipalib/plugins, and replace 'from ipalib.plugins' with 'from ipaserver.plugins ..'.
You can also find a code example which is adding the employee number field to the User Details facet.
For a modern example of a fully working plugin that extends web UI with an existing attribute see https://github.com/abbra/freeipa-userstatus-plugin
