Let's Encrypt the 389 Directory Server

The following procedure is for installing a wildcard cert and key paid from Let's Encrypt for the 389 Directory Server.

1. Use the 389 Console gui to create a certificate database db and to import the Let's Encrypt certificate chain cert (which will be in PEM format). See secs. 9.1.3.2 and 9.3.3.2 of the Red Hat Directory Server Administration Guide for details.

2. Create a pin.txt file under /etc/dirsrv/slapd-[instance name]:

LInux

Three system configuration parameters must be set to support a large number of open files and TCP connections with large bursts of messages. Changes can be made using the /etc/rc.d/rc.local or /etc/sysctl.conf script to preserve changes after reboot.

1. /proc/sys/fs/file-max: The maximum number of concurrently open files.

fs.file-max = 1000000

2. /proc/sys/net/ipv4/tcp_max_syn_backlog: Maximum number of remembered connection requests, which are still did not receive an acknowledgment from connecting client. The default value is 1024 for systems with more than 128Mb of memory, and 128 for low memory machines.

net.ipv4.tcp_max_syn_backlog = 3240000

3. /proc/sys/net/core/somaxconn: Limit of socket listen() backlog, known in userspace as SOMAXCONN. Defaults to 128.

net.core.somaxconn = 3240000
