I'm trying to set up an OpenLDAP server on CentOS Stream 9, currently the server is only used to host a Wiki.JS wiki. I've installed the OpenLDAP server and client packages through yum without any problems but when I try to start slapd services it fails, the log is as follows:

The server is a fresh install of CentOS stream 9, other than the installation on Wiki.JS and has only been set up within the last couple of weeks so should all be on most recent versions.

  • Something here doesn't add up: centos 9 doesn't include OpenLDAP server packages. From where are you installing these packages? – larsks Aug 19 '22 at 11:32
  • @larsks The OpenLDAP packages are installed from EPEL – mrenshaw Aug 22 '22 at 08:47
  • That looks like a bug in the EPEL repository. Those packages need to be rebuilt. You should file a bug with EPEL. – larsks Aug 23 '22 at 04:15
