Subject [jira] [Created] (HADOOP-8381) Substitute _HOST with hostname for HTTP principals
Date Thu, 10 May 2012 00:46:52 GMT
Benoy Antony created HADOOP-8381:

             Summary: Substitute _HOST with hostname  for HTTP principals 
                 Key: HADOOP-8381
                 URL: https://issues.apache.org/jira/browse/HADOOP-8381
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: security
    Affects Versions: 0.22.0
            Reporter: Benoy Antony
            Assignee: Benoy Antony
            Priority: Minor
             Fix For: 0.22.1

SPNEGO based Web Authentication uses HTTP/fqdn@REALM as the kerberos principal for each host.
Since it is difficult to modify the config for each host, a substitution feature where _HOST
gets replaced by fqdn is implemented. 
The task is to provide similar feature for the kerberos principals used for SPNEGO principals
