Cannot Assign OpenID Connect Application to Administrators
We have several custom Web OpenID Connect applications. We would like to assign administrator access to individuals for management of these apps. Unfortunately, the autocomplete dropdown does not contain these applications. We can only assign the template "Open ID Connect Client" which would give access to administer all applications.
Unfortunately this is not possible today to assign a sepcific instance of an application definition. As a consequence you are seeing that by giving application admin access to an admin user, they will be able to admin access to all versions/types of the app definition.
Can I suggest you go to the Okta support site, select Community, then Ideas and post you enhancement request there for others to help vote up this idea please?
