I have an openldap 2.4 server on centos 6 whose confg I copied from those I have running under openldap 2.3 servers on centos 5 machines.
On openldap 2.3, specifying TLSCACertificateFile, TLSCertificateFile and TLSCertificateKeyFile with correct values makes the server listen on port 636. This is not the case on the openldap 2.4 setup.
I have configured it with loglevel -1 but I have not seen any clue as to what might be wrong and reading the openldap 2.4 manual doesn't indicate if any of the other TLS related parameters are now mandatory. I don't think so though because if I run the service manually, using "# /usr/sbin/slapd -u ldap -h "ldap:/// ldaps:/// ldapi:///"", the server does listen on port 636 and I can query it using "ldapsearch -H ldaps://myserver:636".
Is there something I am missing to get the server to listen on port 636 without having to always launch it manually? Is this linked to centos 6 or openldap 2.4?
