Importing Kerberos Keys (CLI)

Use the following procedure to import Kerberos keys that were created on the KDC. The keys are then stored in the appliance keytab. This task does not require login credentials on the KDC. Descriptions of each property are located in Kerberos Service Properties and Kerberos Properties and Logs.

Before You Begin

Ensure that you have enabled the Kerberos service, set the realm, and identified the KDC(s) as described in Creating a Kerberos Realm (CLI).

1. Go to configuration services kerberos importkeytab and enter show to view the properties.

   hostname:configuration services kerberos importkeytab (uncommitted)> show
   Properties:
                             url = (unset)
                            user = (unset)
                        password = (unset)

2. Enter set url= and the URL of the Kerberos keytab file.

   hostname:configuration services kerberos importkeytab (uncommitted)> set url=http://akbuild1/shares/export/123456/demo.keytab
                             url = http://akbuild1/shares/export/123456/demo.keytab

3. Enter set user= and the user name for URL access.

   hostname:configuration services kerberos importkeytab (uncommitted)> set user=myusername
                            user = myusername

4. Enter set password= and the password for URL access, and then enter commit.

   hostname:configuration services kerberos importkeytab (uncommitted)> set password=letmein
                        password = *******
   hostname:configuration services kerberos importkeytab (uncommitted)> commit
   Transferred 718 of 718 (100%) . . . done
   Imported 8 keys.

5. Enter show to view the realms and KDCs.

   hostname:configuration services kerberos> show
   Properties:
                        <status> = online
               allow_weak_crypto = true
   Realms:
   REALM          KDC
   TEST.NET       kdc1.us.oracle.com

6. To view the principals for a realm, select a realm and enter show.

   hostname:configuration services kerberos> select TEST.NET
   hostname:configuration services kerberos TEST.NET> show
   Properties:
                   kdcs = kdc1.us.oracle.com
   Keytab entries:
   NAME            KEYS  PRINCIPAL
   principal-000   4     host/hostname.us.oracle.com@TEST.NET
   principal-001   4     nfs/hostname.us.oracle.com@TEST.NET

7. To view the keys for a principal, select a principal and enter show.

   hostname:configuration services kerberos TEST.NET> select principal-001
   hostname:configuration services kerberos principal-001> show
   Properties:
                    name = nfs/hostname.us.oracle.com@TEST.NET
   Keys:
   KEY       KVNO   ENCTYPENO   ENCTYPE
   key-000   28     18          AES-256 CTS mode with 96-bit SHA-1 HMAC
   key-001   28     17          AES-128 CTS mode with 96-bit SHA-1 HMAC
   key-002   28     16          Triple DES cbc mode with HMAC/sha1
   key-003   28     23          ArcFour with HMAC/md5
   key-004   28     24          Exportable ArcFour with HMAC/md5
   key-005   28     3           DES cbc mode with RSA-MD5
   key-006   28     1           DES cbc mode with CRC-32

   Legend for column headings:

   • KEY = Key name

   • KVNO = Key version number

   • ENCTYPENO = Encryption type number

   • ENCTYPE = Encryption type

8. To view the properties of a key, select a key and enter show.

   hostname:configuration services kerberos principal-001> select key-003
   hostname:configuration services kerberos principal-001 key-003> show
   Properties:
                  principal = nfs/hostname.us.oracle.com@TEST.NET
                       kvno = 28
                    enctype = ArcFour with HMAC/md5
                  enctypeno = 23
