I did above commands, still this issue is not resolved. Failed to stop krb5kdc,kadmin services and also i cant able to destroy. When i destroy make it shows no such entry in database shows.

You will need to set up a cron job to run this script at the intervals you decided on earlier see Database propagation. You may encounter the following error messages. For a more detailed discussion on possible causes and solutions click on the error link to be redirected to Troubleshooting section. Once your KDCs are set up and running, you are ready to use kadmin to load principals for your users, hosts, and other services into the Kerberos database.

This procedure is described fully in Adding, modifying and deleting principals. You may occasionally want to use one of your slave KDCs as the master. See the following section for the instructions. Assuming you have configured all of your KDCs to be able to function as either the master KDC or a slave KDC as this document recommends , all you need to do to make the changeover is:.

If you expect your Kerberos database to become large, you may wish to set up incremental propagation to slave KDCs. See Incremental database propagation for details. Warning The Kerberos system relies on the availability of correct time information. Ensure that the master and all slave KDCs have properly synchronized clocks. It is best to install and run KDCs on secured and dedicated hardware with limited access.

If your KDC is also a file server, FTP server, Web server, or even just a client machine, someone who obtained root access through a security hole in any of those areas could potentially gain access to the Kerberos database.

Note For the purpose of this document we will use the following names: kerberos. EDU - realm name. An example krb5. An example kdc. Note If you choose not to install a stash file, the KDC will prompt you for the master key each time it starts up. EDU"; assigning "default". EDU" created.

Note Assuming you are setting the KDCs up so that you can easily switch the master KDC with one of the slaves, you should perform each of these steps on the master KDC as well as the slave KDCs, unless these instructions specify otherwise. The following files must be copied by hand to each slave see MIT Kerberos defaults for the default locations for these files : krb5. Note If you expect that the master and slave KDCs will be switched at some point of time, list the host principals from all participating KDC servers in kpropd.

Propagation failed? Disable the cron job that propagates the database. After a new master key is added, it should be propagated to slave servers via a manual or periodic invocation of kprop. Sets the activation time of the master key specified by mkeyVNO. Once a master key becomes active, it will be used to encrypt newly created principal keys. If no time argument is given, the current time is used, causing the specified master key version to become active immediately. The format for time is getdate time string.

List all master keys, from most recent to earliest, in the master key principal. The output will show the kvno, enctype, and salt type for each mkey, similar to the output of kadmin getprinc. Delete master keys from the master key principal that are not used to protect any principals. This command can be used to remove old master keys all principal keys are protected by a newer master key.

Update all principal records or only those matching the princ-pattern glob pattern to re-encrypt the key data using the active database master key, if they are encrypted using a different version, and give a count at the end of the number of principals updated. If the -f option is not given, ask for confirmation before starting to make changes.
