Sorry, it looks like I forget to paste the presentation of my issue on reportbug.
I used to use sudo-ldap on Stretch to grant some rights to some users on my servers. I recently upgrade one of these servers to Buster, and now sudo doesn't work anymore. It's always the same error : "ldap_sasl_bind_s(): Can't contact LDAP server". Which is interesting is that ldapsearch works when I try something like this : ldapsearch -x -H ldaps://server2.mydomain.com:636 -b "ou=SUDOers,dc=mydomain,dc=com" Also ldap.conf and sudo-ldap.conf are identical.
