I am attempting to create a multiple domain email server using postfix and cyrus-imap on CentOS Stream 8. It will includes a web back end similar to cyradm. Now I am stuck on mysql or mariadb support for pam. I am not able to find a pam_mysql rpm that will install on CentOS 8. I have a previous version working on CentOS 7. On CentOS 7 I am using pam_mysql 1:0.7-0.20.rc1.fc23 and all is working and has been for a number of years. I found pam_mysql-0.8.1-0.6.fc32.x86_64.rpm, but when I attempt to install it, it says it needs libcrypt.so.1 and it appears CentOS Stream has libcrypt.so.2 Any pointers either where to find pam_mysql, or some other solutions, for CentOS Stream 8? Note that I have epel-release installed and enabled, though epel-playground is disabled, and I am using Remi's repos to install php 7.4.
