I canīt start our LDAP Server with TLS Support.

We use SLES12 SP1 and a self signed CA. (root Ca and Intermediate)

The LDAP Server is on Port 389 up and running.

1. I Create the certificate chain an import to the Server:
cat intermediate.cert.pem ca.cert.pem > ca-chain.cert.pem
copy the ca-chain.cert.pem to /etc/pki/trust/anchors on the Server, and with

import the ca chain.

I see boot, the root ca and the intermediate now at /etc/ssl/certs (link to /var/lib/ca-certificates/pem)

2. Step: I import the Server Certificate p12 (incl.FQDN - commonName)via Yast and Common Server Certificate - Yast: Certificate has been imported

Now I have at
a servercert.pem and a serverkex.pem file.

3. Step: Config TLS Settings via Yast at the running Server

I use the intermediate ca from
and the certificate and the key from
and finish the TLS Config.

I use "Softerra LDAP Administrator" for LDAP administration. The Connect to the the Server over 389 work fine. over 636 "no server" error

At Yast Authentication Server Configuration
Checking LDAP connectivity to the provider failed.

"StartTLS operation failed"
"Connect error: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed (self signed certificate in certificate chain)"

Thats right - it is a self signed certificate installed on /etc/pki/trust/anchors

Where is my fault? What is my fault?
Thanks for your replay
