Once a new entry has been created for an attribute in the Active Roles Web Interface under customizations, it will be available in the list displayed under Form Editor | Add Entry | Select.
However, it is not possible to remove the entry from the list if you no longer need it. Even an entry for a virtual attribute that was deleted in Active Roles will still appear in the list.
Also, an entry for an AD or virtual attribute that was created using custom Display Specifiers will appear in the list under the name taken from Display Specifiers once created. Even if you change or delete the corresponding Display Specifier later, the entry cannot be changed or removed.
This will not cause any issues if the entry is not used on any forms.
Ensure the entry is removed from all Forms it was previously added to in the Active Roles Web Interface under Customizations.
Additional information on configuring form customizations can be found in the ActiveRoles Server Web Interface Administrator Guide.
