Hello,

I'm trying to upgrade an openLdap server from Fedora Core 13 (openldap-servers-2.4.21-11) to Redhat Enterprise 6 (openldap-servers-2.4.23-15.el6.x86_64).
In this new setup,  my local bdb backend works: I can query the LDAP server on this backend using an "ldaps://" connection (it is using a server certificate).

However, the Syncrepl replication process fails to establish the "ldaps://" session to my syncrepl-providers.
Indeed, the TLS layer complains that my _server's certificate_ isn't a valid _client certificate_ (with error 8101 - SEC_ERROR_INADEQUATE_CERT_TYPE): but I don't want client-side authentication!

In the past syncrepl didn't try to use the server certificate as a client certificate, and I haven't seen any reference to this in the documentation.
I first thought it could have been related to ITS#6791 but I don't think so anymore because it only affects Syncrepl.

Do you think I've missed something in the setup?

Thanks in advance,
Thibault
