A person's acknowledgements and certification information is published in LDAP and CAS and may be utilized by an application to determine if a person is authorized to access the applications. For example, if a person has not completed an on-line UH General Confidentiality Notice, your application can determine this fact from the returned CAS attributes and provide the user with a message explaining why they are not currently authorized for access.
See Data Element - UH Acknowledgement (uhAcknowledgement) for more details.
