iSeries NetServer™ supports guest user profiles (this is also known as an anonymous user profile). The iSeries server can automatically map an unknown user to the guest user profile if you specify a guest user profile. Your network administrator can specify and change the guest user profile that iSeries NetServer uses, if necessary, on the iSeries NetServer Advanced - Next start page within iSeries Navigator. In general, the guest user profile should have very few authorities because the guest user is considered a non-trusted user.
