You can configure Denodo Express to work with Kerberos. As you can read in the [Limitations of the Denodo Express License](https://community.denodo.com/docs/html/browse/7.0/platform/installation/appendix/limitations_of_the_denodo_express_license/limitations_of_the_denodo_express_license), Kerberos isn't one of them.
It'll work with just one account, but you won't be able to create new accounts because of the Denodo Express limitations.
Also, take into account the steps you should follow to configure [Kerberos Authentication](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/server_administration_-_configuring_the_server/kerberos_authentication/kerberos_authentication).
Hope this helps!
