For development of the community version of Kolab, it is helpful to have nightly built packages of the master of https://git.kolab.org.
Note: these packages are only meant for development and testing, not at all for production use!!!
It is recommended to do a fresh install of the machine, when you want to go back to the Kolab Community version packages, without the nightly packages.
CentOS 6
