WebGUI access to the MQ Appliance network device must map the authenticated identity to the user account for PKI-based authentication.
Authorization for access to any MQ Appliance network device requires an approved and assigned individual account identifier. To ensure only the assigned individual is using the account, the account must be bound to a user certificate when PKI-based authentication is implemented.
Log on to the MQ Appliance CLI as a privileged user. Verify the MQ Appliance is configured to support PKI-based user authentication.
Verify an SSL Server Profile is associated with the WebGUI (CLI). Enter: co show web-mgmt
[Note the name of the ssl-server]
Display the parameters of the ssl-server (CLI). Enter: co crypto ssl-server show
[Note the name of the valcred]
Display the certificates in the ValCred (CLI). Enter: co crypto valcred show
