title: Is it possible to use a keytab for group of user in AD
body: <p>I am using kerberos with Hadoop environment, and I use keytab file to give authentications to different user. Now I have some users to them i have to give same privilege to all them.<br/>
  So i created a user group and generated a generic keytab file for that active directory group, but failed to validate the keytab file. It gives me an error as mentioned below:<br/><br/> <em>kinit: Client 'xyz@BIGDATA.LOCAL' not found in Kerberos database while getting initial credentials</em><br/><br/>
  Now the question is, is there possibility to use a keytab file for group in active directory or should i have to use any other way to achieve the same?</p>
