OpenLDAP with TLS, ppolicy and master-master replication on RHEL6.3
This post has been dusting on a draft shelf for too long. No reason to keep it there any loger. Below is the list of instructions which once followed would help anyone to end up with an OpenLDAP server on RHEL 6.1 (should work perfectly well with CentOS too). There is nothing special about it […]
