hi,
doing a clean install of kolab 3.3
clean install of centos 7
lamp install with mariadb and /usr/bin/mysql_secure_installation
yum install kolab
resulted in
Error: Package: kolab-3.1.8-4.2.el7.kolab_3.3.noarch (Kolab_3.3)
           Requires: mysql-server
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
