Thank you very much! My system-auth file is : #%PAM-1.0 # This file is auto-generated. # User changes will be destroyed the next time authconfig is run. auth required /lib/security/$ISA/pam_env.so auth sufficient /lib/security/$ISA/pam_unix.so likeauth nullok auth required /lib/security/$ISA/pam_deny.so account required /lib/security/$ISA/pam_unix.so account sufficient /lib/security/$ISA/pam_succeed_if.so uid < 100 quiet account required /lib/security/$ISA/pam_permit.so password requisite /lib/security/$ISA/pam_cracklib.so retry=3 password sufficient /lib/security/$ISA/pam_unix.so nullok use_authtok md5 shadow nis password required /lib/security/$ISA/pam_deny.so session required /lib/security/$ISA/pam_limits.so session required /lib/security/$ISA/pam_unix.so </div>What I mean is that " PHP application send the password to the C CGI program which performs the authentication using PAM". but what is it the different with the "does the user send the password to the C CGI program which performs the integration using PAM"? I think your method do make sense that I will use SSL to send the password to a CGI program ,and then the CGI program performs the authentication using PAM. But it happens at the user login. After login, I need save the username and password in the PHP session, and for security , I think I should save the hashed password with MD5 which can be sent back by CGI program. When user performs some operations on the PHP application , for security, I need to send the username and password to CGI program which will auth it again, and then do some operations, but at this time the password I sent is MD5 password , so i need C CGI program auth the MD5 password. I don't know how to do it or whether my method is correct. Thank you very much!
