[Pam-mysql-general] change password error for non root process

[<and...@79...>]

Hello

i have tried to use pam-mysql with "poppassd" to change passwords for e-mail 
users located in a mysql database. For security reasons i don´t run "poppassd" 
as root and stumbled over line 1125 in pam-mysql (ver. 0.5) where the following 
statement appears :

if (!db_checkpasswd(&auth_sql_server,user,oldpass))
  retval = PAM_SUCCESS;
else
  retval = PAM_AUTHTOK_ERR;


With this i´m not able to change my password if "poppassd" isn´t "root".

If i change it to the inverse logik : 

if (db_checkpasswd(&auth_sql_server,user,oldpass))
  retval = PAM_SUCCESS;
else
  retval = PAM_AUTHTOK_ERR;

It works.

Any comments??

Regards

Andreas
