pam_authenticate failed, result 7 with sqwebmail

I have problems authenticating in sqwebmail and I ran a debug and got this error in the logs. I try and use authpwd or authshadow but they are not installed (I believe sqwebmail does this if pam is installed). The username is correct, as is the home directory.

Any ideas how to fix this?

thanks

I figured it out. I found in the /etc/pam.d directory there was not webmail service. So I copied ppp and it worked.
