Okta Universal Directory has been available upon request for months. Now, all new customers will automatically get features from Universal Directory, depending on what edition you purchase. (Visit okta.com for more information on Okta Editions).
Learn the details of how UD enables more advanced authentication and provisioning scenarios in About Universal Directory.
Existing customers will be enabled through a rolling release of the feature. If you want the benefits of UD sooner, call Okta support to have it enabled today.
