5. Configuring PAM

Now we need to get sure that PAM knows how to authenticate the Cyrus users

You have to create the file /etc/pam.d/imap with the following entries:

auth sufficient pam_mysql.so user=mail passwd=secret host=localhost db=mail table=accountuser usercolumn=username   passwdcolumn=password crypt=1

auth sufficient pam_unix_auth.so

account required pam_mysql.so user=mail passwd=secret host=localhost db=mail table=accountuser usercolumn=username passwdcolumn=password   crypt=1

account  sufficient       pam_unix_acct.so

The lines containing pam_unix_auth.so and pam_unix_acct.so are only needed if you are migrating from WU-IMAP to Cyrus. This allows you to authenticate with its old unix-password AND its new mysql-based password.

To use the other services provided by cyrus and smtp-authtication you need to copy the file so that they match the service-ID

cp /etc/pam.d/imap /etc/pam.d/pop
cp /etc/pam.d/imap /etc/pam.d/sieve
cp /etc/pam.d/imap /etc/pam.d/smtp
