I had a couple of questions regarding some authentication solutions. We have interest in implementing either ADFS or LDAPS. I believe that out of the box, the only authentication solution that is supported is generic LDAP. Is it possible to implement either of these authentication solutions? If not, would this be considered an enhancement request?
You can custom the authentication service by extensible plugin.
For more information, please refer the document included in ExtensibilityPack>ReferenceImplementation>LDAPIntegrations. You can implement your own logic to authenticate not only by LDAP.
