Hello,
I'm trying to configure an openldap with TLS so that all connections are encrypted.
Here's the revelent part of my slapd.conf:
TLSCipherSuite HIGH:MEDIUM:+SSLv3
TLSVerifyClient never
TLSCertificateFile /etc/ldap/ssl/server.crt
TLSCertificateKeyFile /etc/ldap/ssl/server.key
Here's my ldap.conf:
URI ldaps://my.server.ltd
BASE dc=my,dc=server,dc=ltd
LDAP_VERSION 3
#SIZELIMIT 12
#TIMELIMIT 15
#DEREF never
ssl start_tls
ssl on
TLS_CIPHER_SUITE HIGH:MEDIUM:+SSLv3
While starting slapd with:
slapd -h 'ldaps:///' -g openldap -u openldap -d 16383
and trying to connect to it with:
ldapsearch -Z -d 16383 -LLL -b cn=admin,dc=my,dc=server,dc=ltd -w "foo.bar" -S cn -h my.server.ltd -p 636 cn
I have these logs :

I really don't know what to do. My certificates are correct I guess, as we're using them in apache for https... For information, they are self-signed.
Any help would be great.
Thank you!
Best regards,
C.
