Setting the FBA Preference
If Creo Packages will be used with a Windchill server that uses forms-based authentication (FBA), you must set a preference on the Creo Packages client. In the wpc_preferences.txt file, set the preference as follows:
windchill.auth.mode=PROTOCOL_AUTH
CAC/PKI or SSO Client Authentication
Creo Packages do not support CAC/PKI or SSO configurations. They support protocolAuth as a solution which do not use SSO and other authentication configuration.
To avoid the authentication program uncomment the windchill.auth.mode=PROTOCOL_AUTH from wpc_preference.txt.
