I am not sure if this message already went out. I really need a new mail server. Sorry? Hi I am trying to authenticate my mail server with samba ad. The only problem is that I don?t get it working. root at dna:/data/CA/EasyRSA-v3.0.6# ldapsearch -x -h gaia.rompen.lokaal -D 'vmail' -W -b 'cn=users,dc=rompen,dc=lokaal' Enter LDAP Password: ldap_bind: Strong(er) authentication required (8) additional info: BindSimple: Transport encryption required. I can not read the ldap database. I think it is a certificate problem. I made my own CA agent, and gave samba a server certificate for ldap. But how can I use the public key to read the database?
