Update: I wanted to provide a last update here one last time before moving on to the next topic. When I tried to install LAM I was getting a blank screen when trying to access. I looked at the logs and tried to troubleshoot what the problem was, but it seemed that I was missing something. In the link it showed how to install LAM - LAM - LDAP Account Manager
But my problem was the same problem mrmarkuz was having about mid-way down after the How To explained how to install. In his instructions he mentioned to install nethserver-rh-php71-php-fpm and rh-php71-php-ldap, and change the directive at line 9 (and above) of the file /etc/httpd/conf.d/lam.apache.conf, and to restart the services (systemctl restart httpd rh-php71-php-fpm). Well, for some reason that stood out as the resolution to the issue I had and VOILA, it worked and I was able to log in to the LAM and see the LDAP database after configuring LAM via the web interface. I am now following up with how to make custom attributes as I found near the beginning of this issue. Thanks again for all your help and I look forward to ding the How to for sipXcom LDAP integration. I hope is will benefit someone looking for help with integration. It’s definitely a great solution which is Enterprise worthy. Happy New Year!
