linux - In case of converation error , how to return to the application without checking other methods in pam

Question

Let us say for my application APP , I have added a file in /etc/pam.d/APP and in APP I have defined the following:

    ....
    ....
    auth required method1
    auth required method2
    auth sufficient method3
    ....
    ....

In case of a conversation failure in method1 , how to return without calling pam_sm_authenticate in method2 and method3.

Thanks

Answer 1

如果你做第一行：

auth requisite method1

然后 pam 将立即返回失败。
