CGIPassAuth not usable in CentOS 7.3.1611 because of old Apache version
CGIPassAuth parameter is only usable since Apache 2.4.13: https://httpd.apache.org/docs/2.4/fr/mod/core.html#cgipassauth
In LemonLDAP::NG 1.9.10, this new parameter is added in portal, but when installing it on default up-to-date CentOS 7.3.1611, apache restart fails because the newest version of Apache on this OS is Apache 2.4.6.
The error is: {noformat} httpd: Invalid command 'CGIPassAuth', perhaps misspelled or defined by a module not included in the server configuration {noformat}
