I am using AfterLogic as a webmail client and my users would like to be able to change their passwords within this.  Afterlogic says it will use POPPASSD for password changes, so I am attempting to install it but am having issues with the pam.d poppassd config file.  I'm not sure the best way to set this up as I'm very green in how pam.d works. I've tried a number of configurations, but everytime I run poppassd it will not accept my old password.  Here is what is in my /etc/pam.d/poppassd file currently:

auth required /lib64/security/pam_unix_auth.so shadow nullok
account required /lib64/security/pam_unix_acct.so
password required /lib64/security/pam_cracklib.so retry=3
password required /lib64/security/pam_unix_passwd.so use_authtok nullok

Here is what Poppassd tells me - I am using the correct password for the account:

200 poppassd v1.8.5 hello, who are you?
user marcus@******.ca
200 Your password please.
pass ******
500 Old password is incorrect.

I've confirmed that the .so modules do exist in these locations.  I think the issue is that it needs to get the password from mySQL and I'm unsure how to get it to communicate with that.  I've been googling for hours and after trying numerous variations for pam.d I am giving up!  If anyone can point me in the right direction I'd be grateful!
