SSL Workflow between Client and Server


Below is the flow control between server and client to establish client authentication with user certificate binary verification.

  1. Client sends client client_hello to Server

  2. Server responds with server_hello, and its certificate. Server requests the client certificate

  3. Client replies with its certificate and exchanges the session key

  4. SSL connection established

  5. Server searches the subject DN of the client certificate. In our example here it is cn=USER.1,ou=people,<SUFFIX_DN>

  6. From the user entry cn=USER.1,ou=people,<SUFFIX_DN>, server fetches the value of "userCertificate:" attribute which is the exact copy of the client's certificate. Server uses this value for verification of the the client's identification for binding to the directory.

  7. After authentication, the LDAP operation will be performed as usual
