There could be various reasons why you cannot access ARDC Online Services (RDA Registry, DOI, Handle) such as:
You are trying to login using local credentials
If you have previously been using the ARDC Demo environment during a training course or the Test environment for a UAT, you will have been given a built-in account. Your built-in credential is not available to users in the PRODUCTION environment. When you are in the 'AAF Rapid Connect' tab of the RDA Registry login screen, you are expected to login using your AAF account.
Please refer to How to login to Online Services for detailed instructions.
You do not have a valid username and password from the AAF
Access to these ARDC online services is via a username and password that are valid within the Australian Access Federation (AAF). If you are unfamiliar with the AAF there is an excellent video animation explaining how this works at https://www.aaf.edu.au/about/
Please refer to How to obtain an AAF account for more information or send a mail to services@ardc.edu.au
