And even better you should use ldapi:// [1] for local access. http://tools.ietf.org/html/draft-chu-ldap-ldapi Ciao, Michael.

All hostnames and IP addresses used by clients have to be listed in the subjectAltName extension. Ciao, Michael.

I have followed this link <http://stackoverflow.com/questions/21488845/how-can-i-generate-a-self-sig...;. I update openssl.cnf file manually and added the ip address of other client machine. Then i generated ssl certificate. Now accessing ldaps:// platalytics.com:636 from other client machine (i also have added platalytics.com in /etc/hosts file) but unable to access it from external ip address. What i'm missing now?

Do we need to have CA certificate/server key on other client machine as well? If yes, then how can we achieve that?
