title: Making SASL(with GSSAPI) enabled client and server with LDAP+kerberos as authenticator? (Single Sign on SSO sytstem)
body: <p>I have successfully installed ldap and kerberos. I was also able to make a simple c program with SASL/GSSAPI to search data in my ldapserver?</p>
  
  <p>But I was not find any article (that I can follow easily) on how to use the the single sign on functionality in a client server system? I am not even sure how the communication between client and server happens in SSO.</p>
  
  <p>How would a server know that client is a valid client?<br>
  Are there any sample examples/tutorials to make such a system?</p>
  
  <p><strong>Edit:</strong>
  The server can be as simple as receiving hello from authenticated client. So client should have kerberos ticket and server should verify the ticket if it is valid or not.</p>
