MySQL/PamMd5

Mamono> I'm trying to use pam_mysql to authenticate vsftpd against a mysql database and it works with cleartext passwords but when I try encrypted ones it fails..

levin> try changing MD5Data()'s to MD5()'s and include openssl/md5.h

levin> I'm wondering where that MD5Data function is defined and why it doesn't do anything

Mamono> pam_mysql.c:/* AFAIK, only FreeBSD has MD5Data() defined in md5.h

levin> open up your mysql_com.h file and check the function definition for make_scrambled_password

Mamono> well, there is this: void make_scrambled_password_323(char *to, const char *password)

Mamono> yep, changed it to the 323 function and now it works with mysql password

Mamono> I went one step further and added another option to the crypt option that let's me use crypt=4 for mysql 4.1

Mamono> looks like 4.1 support is in the CVS version

Here is a patch for MySQL 4.1:

If you add "crypt=4" in your pam config it will use the 4.0 and less password() function
