fyi, my upgrade from 7.2.4 to 7.2.5 went off without a hitch.

After that I manually removed the 2.2.1 WebApp components with yum and installed the Kopano WebApp components the same way. After configuring Kopano webapp to connect at /var/run/zarafad/server.sock it ran out of the box.

Will continue to test, Bravo and thanks.
