Step 1 - Identifying the TA

To register a new Trust Authority click the New button. The following screen is displayed:

Each item in the screenshot is described below:

Items	Description
TA Status	This can have a value of Active or Inactive or Revoke. ADSS Server ignores any inactive Trust Authorities when processing service requests. Setting an Authority to inactive is a convenient way of suspending the use of a particular trust authority rather than deleting its record.
TA Certificate	Identifies the Trust Authority’s digital certificate. Click Browse to locate the Authority’s certificate and import it. Note: The certificate file must only contain the authority’s certificate and not a complete chain. DER, PEM or Base64 formats are supported.
TA Distinguished Name	All the Distinguished Names that are associated with the certificate selected in the above field are shown in this text area.
TA Friendly Name	A unique name for the Trust Authority (TA). The name of the Trust Authority is automatically set to the Common Name (CN) of the imported TA certificate. You can also change the TA Friendly Name to something other than the CN of the TA Certificate.
TA Registration Purpose	Used to select the purpose(s) for which this Authority certificate can be used (more than one purpose can be selected): CAs – to trust CRLs and Certificates issued by the CA (e.g. certificates issued to OCSP and TSA servers). OCSP Responders – to trust self-signed OCSP Responder certificates or those not issued by a trusted CA. CRL Issuers – to trust CRLs (but not certificates). Time Stamping Authority – to trust self signed Time Stamp Authorities or those not issued by a trusted CA. CA for verifying TLS client certificates - to trust TLS client certificates. Country Signing CA - to trust the certificates, CRLs and master lists issued by a Country Signing CA (CSCA).

When registering a trusted Authority with purpose other than CA, the wizard finishes after this screen and no more details are required. While registering the a CA, additional information is required and the additional steps described below must be followed before the wizard completes.
