Hello, I'm using samba 4.7.3 to run an AD and I'm currently having issues with the MIT kerberos because it stops some time after starting (and apparently working correctly) without logging nothing out of the ordinary. My setup has 2 DC: one in an ubuntu 12.04 with version 4.1.9 (which we're migrating from) and the one I mentioned in CentOS 7 (which will be the only DC in the future).

Some background information. I have used Debian with Asterisk for several years. Have encountered zero problems. I am now trying to setup an Asterisk on a CentOS7 box using VMWare Workstation. I am brand new to CentOS and RHEL so I may be missing something obvious. I am installing CentOS Minimal Install and Asterisk from Source. (I have installed Asterisk from Source on Debian hundreds of

But when I set mail_full_filesystem_access = no it stops authorization for postfix with this message: <pasek at valbek.cz>: Command died with
