It is some + property, such as a <emphasis>Kerberos</emphasis> ticket, or a + supplementary group membership that make up the uniqueness of a + given user. On a Linux system the user's <emphasis>UID</emphasis> + and <emphasis>GID</emphasis>'s are credentials too. However, it + has been decided that these properties (along with the default + supplementary groups of which the user is a member) are credentials + that should be set directly by the application and not by PAM. + Such credentials should be established, by the application, prior + to a call to this function.
