Setup basic 389-DS server

To setup basic 389-DS server use following steps:

1. yum -y install epel-release
2. If LDAP server is being setup on VM or base machine then do the following: (Not useful for container based setup)
   1. Edit '/etc/sysctl.conf'

      net.ipv4.tcp_keepalive_time = 300
      net.ipv4.ip_local_port_range = 1024 65000

   2. In '/etc/security/limits.conf' add:

      *               soft     nofile          8192
      *               hard     nofile          8192

   3. Edit '/etc/profile' and at the end append

      ulimit -n 8192

   4. Edit '/etc/pam.d/login' and after last session required line add

      session    required     pam_limits.so

3. Create ldapadmin user and set its password
4. Install 389-ds and openldap-clients using:

   yum install -y 389-ds openldap-clients

5. Ensure that FQDN resolves to IP and with help of /etc/hosts IP resolves to FQDN. Without this setup fails. Even after setup while running the server this is necessary for server to continue working.
6. Run 'setup-ds-admin.pl' and enter appropriate values to setup the server
7. Allow incoming TCP connections on port 389, 636 and 9830 in firewall
8. Configure 389-ds to automatically start on system boot using:

   chkconfig dirsrv-admin on
   chkconfig dirsrv on

To connect to server on administrators machine

1. Install 389-ds (and not just 389-console)
2. Use command:

   389-console -a http://<server-fqdn-or-ip>:9830/
