Issue ID: 9568 Summary: ldapsearch command not working with ECC certificates Product: OpenLDAP Version: 2.4.56 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: client tools Assignee: bugs@openldap.org Reporter: adisheshsm@gmail.com Target Milestone: ---

Hi, ldap server is configured with ECC certificate. ldap server certificates are generated using openssl command.

mTLS is enabled on ldap server side.

for ldap client ldapsearch purpose, we have tried client certs using RSA and ECC. when server is configured with ECC certs, client is not able to connect to server.

please let us know if openldap clients work with ECC certificates (prime256v1 curve).

we tried below scenarios: both are not working 1. openldap server and client with ECC certificates 2. openldap server with ECC certificate and client with RSA certificate.

we are getting below errors.

--------client side details----------------- ---------------------------------------- $ cat ~/.ldaprc TLS_CACERT /tmp/ec_cacert.pem TLS_CERT /tmp/rsa_client.pem TLS_KEY /tmp/rsa_client.key TLS_REQCERT never TLS_PROTOCOL_MIN 3.2
