kerberos authentication steps

Http://blog.163.com/jobshot/blog/static/947091982008118105524719/ I. Basic Principles Authentication solves the problem of "how to prove that a person is indeed the one he or she claims. For how to authentication, we adopt this method: If a secret exists only in A and B, then one person claims to B that he is, B asks a to provide this secret to prove that this person is the he or she claims. This proc

The Microsoft Windows Server 2003 operating system implements the authentication protocol for Kerberos version 5. Windows Server 2003 also extends public key authentication. The client for Kerberos authentication is implemented as a SSP (security support provider) that can b

log on to the Server. 4. One application instance For A clearer description of the Kerberos 5 authentication protocol, the example in the actual application (the specific example can be seen in the actual application below): Assume that A Local Area Network, its DNS domain is the9.com; Realm is THE9.COM; Kerberos databases, AS and TGS servers are all on the host

not confirmed that it is not accessing a phishing service. To verify the server on the client, the Service needs to encrypt the decrypted Authenticator with the Service Session Key again and play it to the client. The client decrypts the client with the cached Service Session Key. If the client is identical with the previous content, it can prove that the server you are accessing has the same Service Session Key as the client, this session key is not known to outsiders (the above content corres

Vi. User2User Sub-Protocol: effectively safeguards Server security Through the introduction of three Sub-protocols, we can fully master the entire Kerberos authentication process. In fact, in the Windows 2000 era, Kerberos-based Windows Authentication is implemented according to this workflow. However, as I mentioned a

role of the TGS, isn't it better? In fact, this will not bring about the essential difference, because as and TGS can be regarded as one, because as and TGS constitute a Kerberos server. Kerberos ApplicationConsiderations: The Kerberos protocol is relatively cumbersome. To obtain a service ticket, you must first enter a password, get the as

the files decompressed by the tar package. Decompress hadoop-2.3.0-cdh5.0.2.tar.gz. Suppose you decompress the package to the/opt directory and rename the hadoop-2.3.0-cdh5.0.2 directly to hadoop (now your cdh root directory is/opt/hadoop). Let's make the following changes: Copy the bin-mapreduce1 so the file to the bin, for the same file, directly overwrite it. The following file structure is available in the/opt/hadoop/share/hadoop Folder: Delete the soft link file mapreduce, and create a

transactions in the session process. After the service verifies you, you do not need to use Kerberos-based commands (suchFTPOrRsh) Or perform self-verification when accessing data on the NFS file system. Therefore, you do not need to send a password on the network each time you use these services (the password may be blocked on the network ). Ii. Kerberos authenti
