In the Configurations tab, expand your configuration.
Expand Web Services/Security/Authentication.
In the Mode field, choose the method clients use for authentication. The default is Username Token Profile. You can choose one of the following:
Username Token Profile - Oracle recommends using this authentication mode. It defines how a web service client application can supply a user name and an optional password in the message request that the web service server can use to authenticate the requester's identity.
SAML Token Profile - Security Assertion Markup Language (SAML) defines an XML-based mechanism for exchanging messages that contain security information in the form of assertions.
Cookies - This option requires you to call the Authentication service Login operation to establish a session and obtain a cookie before you can use any other P6 web service.
Note: See the P6 Web Services Programmer's Guide for more information.
