I setup openldap-2.4.23 server

Why?  I'd suggest you start with the current release, 2.4.30.  You may also want to look at <http://www.openldap.org/its/index.cgi/?findid=7197>

That's the openldap version in centos6.2 repo. In production I try to stick with stock versions.

Also I tried all variations of olcTLSVerifyClient: [demand|hard|true] with the same result.

I don't think StartTLS is enabled. I'm wondering if just setting olcTLSCACertificateFile, olcTLSCertificateFile and olcTLSCertificateKeyFile is enough to get StartTLS enabled.
Yes, it is.

It's very frustrating. I'd hate to go to ldaps just because I can't get StartTLS working.

Is there anything else I have to set on the server to get StartTLS working?
Can you provide the exact command line you are using to test the server connection?  Note that if the client is using regular LDAP and not LDAPS nor LDAP+startTLS, the olcTLSVerifyClient: demand setting does nothing.

This is exactly what I'm seeing. I misunderstood the documentation. I thought that when olcTLSVerifyClient is set to demand then a valid certificate is required and the connection will drop if one is not provided.

If you are trying to make the client always use SASL/EXTERNAL auth with a valid client cert, you must first force the server to reject any non-TLS/SSL connection using the sasl-secprops minssf setting.

Yes. I'd like the server to reject any non-TLS/SSL connections. I'll look into the settings you mentioned.

As I was typing this I received a few more answers. Thank you very much.

Last question:
If the FQN of the client is server1.mydomain.com and in the certificate 
the commonName is server1.mydomain.com but
in openldap the DSE is "dc=hr,dc=mydomain,dc=com".

Will that work or the DSE has to match the domain name i.e. "dc=mydomain,dc=com"?

Thank you
