Hi, I am studying PAM. I understood upto “auth sufficient pam_unix.so.”. If credentials are ok then authentication will be successful. And it wont load any other module. But then why pam_succeed_if.so is there? I just did some work on it, I found it is only useful when pam_deny is disable. auth requisite pam_succeed_if.so uid >= 500 quiet Also it is used in “account” module type: account sufficient pam_succeed_if.so uid < 500 quiet Can you please explain me? I saw the documentation too, but didn’t understand the purpose of it. Regards, Neelesh Gurjar I have no special talent. I am only passionately curious !
