Description of problem: When incremental propagation is configured kadmind can not bind to port 754 on master server because that is reserved by portreserve. It would be nice if kadmind in its init script could release this port, similarly as it releases the port 749. Note, that port 754 is released normaly by kpropd, but as kpropd and kadmind can not run in the same time, this would not conflict. IMHO, the this could be fixed by just adding the following line into /etc/init.d/kadmin: [ -x /sbin/portrelease ] && /sbin/portrelease krb5_prop &>/dev/null || : Version-Release number of selected component (if applicable): krb5-libs-1.10.3-42.el6 How reproducible: always Steps to Reproduce: 1.
