tify who the client wishes to be GSSName userName = manager.createName("duke", GSSName.NT_USER_NAME); // Identify the name of the server. This uses a Kerberos specific // name format. GSSName serverName = manager.createName("nfs/foo.sun.com", krb5PrincipalNameType); // Acquire credentials for the user GSSCredential userCreds = manager.createCredential(userName, GSSCredential.DEFAULT_LIFETIME, krb5Mechanism, GSSCredential.INITIATE_ONLY); // Instantiate and initialize a security context that will be // established with the server GSSContext context = manager.createContext(serverName, krb5Mechanism, userCreds, GSSContext.DEFAULT_LIFETIME);
The server side might use the following variation of this source:
```
 // Acquire credentials for the server GSSCredential serverCreds = manager.createCredential(serverName,  GSSCredential.DEFAULT_LIFETIME,  krb5Mechanism,  GSSCredential.ACCEPT_ONLY);  // Instantiate and initialize a security context that will // wait for an establishment request token from the client GSSContext context = manager.createContext(serverCreds); 
```
