Hi
I've followed the instructions in https://www.openldap.org/doc/admin26/quickstart.html to deploy openldap 2.6.4 on a SLES 15 SP4 system. Once I confirmed that this was working correctly, I moved on to configure TLS, following the instructions in https://www.openldap.org/doc/admin26/tls.html. When I try a connection to the LDAPS port (636), I see the following:
ldpdd040:~ # openssl s_client -connect ldpdd042.hop.lab.emc.com:636 CONNECTED(00000003) 139702302594704:error:140790E5:SSL routines:ssl23_write:ssl handshake failure:s23_lib.c:177:

I'm using this command to start slapd: /usr/local/libexec/slapd -F /usr/local/etc/slapd.d -s 3 -h "ldap:/// ldaps:///"
When I execute the openssl command above, I look in /var/log/messages and see:
2023-05-11T12:51:55.213884-04:00 ldpdd042 slapd[20101]: conn=1000 fd=12 ACCEPT from IP=10.247.229.40:56844 (IP=0.0.0.0:636) 2023-05-11T12:51:55.213944-04:00 ldpdd042 slapd[20101]: connection_get(12): got connid=1000 2023-05-11T12:51:55.214004-04:00 ldpdd042 slapd[20101]: connection_read(12): checking for input on id=1000 2023-05-11T12:51:55.214065-04:00 ldpdd042 slapd[20101]: connection_read(12): TLS accept failure error=-1 id=1000, closing 2023-05-11T12:51:55.214138-04:00 ldpdd042 slapd[20101]: connection_close: conn=1000 sd=12 2023-05-11T12:51:55.214207-04:00 ldpdd042 slapd[20101]: conn=1000 fd=12 closed (TLS negotiation failure) ldpdd0
I've appended these lines to /usr/local/etc/openldap/slapd.conf:
# Added TLS directives # TLSCACertificateFile /var/lib/ca-certificates/ca-bundle.pem TLSCertificateFile /etc/ssl/private/server.cert TLSCertificateKeyFile /etc/ssl/private/server.key #TLSCipherSuite ALL
I can't find any log information that helps me understand what the problem is. I'm using a self-signed server certificate that has the cn using the FQDN of the server.
How can I debug this?
Thanks! tl
Hello list,
if I understand the listed configuration correctly slapd is started with online config and the TLS information is configured in the static config file slapd.conf. Is this kind of mixed configuration valid or do the TLS information have to be configured in corresponding olc-Attributes in cn=config?
