Abstract

• Today, universal cloud computing and digital world cannot exist without virtualization architecture. They are basic tools to support varying demands without sluggish, expensive physical reconfiguration and software stack investment. On the other hand, Information and data are live source of today business in an organization. These data are created more and more every day. Data can be saved, but the weakest link in the cloud security is end point. Users can move on and data can be lost. This can bring more exposure to security threats, no reliable and safety. So, cloud security is becoming an important research topic. To demonstrate the weakness and vulnerabilities of LDAP (Lightweight Directory Access Protocol) server on virtual cloud environment, paper is developed by allowing Kerberos Single-Sign-On with LDAP directory service environment with client/server model in order to prevent third party password sniffing, eavesdropping and stealing password from LDAP database.
