When you use P6 Web Services, you must authenticate your credentials with the server. The server can be configured to authenticate user credentials in one of three methods:
Authentication using UsernameToken
Security Assertion Markup Language (SAML) 1.1
Authentication using HTTP Cookies
Note: UsernameToken Profile (with or without nonce) is the preferred method of authentication. Support for HTTP cookies has been maintained in the current version to avoid rendering code that you wrote against earlier versions of P6 Web Services incompatible with the current version of P6 Web Services. The default method of authentication is UsernameToken Profile with nonce. You use the P6 Administration Application to change the authentication method on the server via the Web Services/Security/Authentication/Mode setting.
