sssd (2.0.0, CentOS 8) with old tls 1.0 only ldap

Question

I can't connect sssd (2.0.0, CentOS 8) with old tls 1.0 only ldap (MacOS X 10.6 server).

Working, so this should be possible:

openssl s_client -connect snow.cologne.intradesys.com:ldaps -tls1

In /etc/openldap/ldap.conf i have the option to set TLS_PROTOCOL_MIN 3.1 (= TLS 1.0)

But looking at: man sssd-ldap i have a lot of ldap_tls_... parameters, but non to downgrade to TLS 1.0

So i get /var/log/sssd/sssd_default.log:

/var/log/sssd/sssd_default.log[sss_ldap_init_sys_connect_done] (0x0020): ldap_install_tls failed: [Connect error] [error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol]

Answer 1

Just found another and more appropriate solution with the same effect.

update-crypto-policies --set LEGACY
systemctl restart sssd

Job done.
