Verifying Kerberos is Functional

In the above example, SOFTNAS.LOCAL is the full domain name. Log in to a command shell using SSH, SoftNAS Console (VMware) or use the Command Shell. To access the command shell from within the SoftNAS UI, go to Settings > General System Settings, which will open a new window with access to the full Webmin console, then choose Others > Command Shell.

Once in the command shell, (whichever method you use) issue the following commands:

•  "kinit" is used to log in as the AD administrator. Note that for best results use the actual domain administrator, not a user with domain admin rights.
  
  
•  Enter the password for administrator@SOFTNAS.LOCAL:

  [root@softnas]# kinit -p administrator

  
  
  
•  Next, list the Kerberos ticket, which proves you successfully logged into AD.

  [root@softnas]# klist

  You should see something like: 
  
  

  Panel
  borderColor black bgColor #f0f0f0 borderStyle solid
  Ticket cache: FILE:/tmp/krb5cc_0 Default principal: administrator@SOFTNAS.LOCAL Valid starting Expires Service principal 01/21/13 17:26:12 01/22/13 03:26:20 krbtgt/

• SOFTNAS.LOCAL@SOFTNAS.LOCAL renew until 01/22/13 17:26:12
