PAM denying valid user

[Kevin Schroeder]

Hello,
    I'm having a problem with PAM denying authentication for a valid user. 
I'm using the pam_mysql method to authenticate a user.  The user exists in 
the database and in checking the query made I can see that the username and 
password are matching at that pam_mysql is returning 7 (PAM_SUCCESS?). 
However, when attempting to log in with IMAP or FTP I get an authentication 
failure error on both.

    Here are the files in /etc/pam.d/

IMAP:
auth required pam_mysql.so user=user passwd=password host=localhost db=wph 
table=accounts usercolumn=username passwdcolumn=password  crypt=0 sqllog=0

FTP:
auth required pam_mysql.so user=user passwd=password host=localhost db=wph 
table=accounts usercolumn=username passwdcolumn=password  crypt=0 sqllog=0
account    required     /lib/security/pam_pwdb.so
session    required     /lib/security/pam_pwdb.so

    Each account has a corresponding UNIX account but by doing the 
authentication via MySQL allows me to more accurately control who can log in 
on what service and allows the individual user to manage their password 
without shell access.

    IMAP is being handled by Cyrus/SASL/PAM.  I'd like to use PAM for all 
authentication needs so I only need to learn one authentication method as 
opposed to learning (or writing) the MySQL authentication for each 
individual program.

    What am I missing to allow the MySQL module to fully authenticate a 
user?

Thanks
Kevin
