Per identity Kerberos v5 configuration

Kerberos v5 options include the ability to select the ticket lifetime as well as renew and forwarding. The Kerberos v5 ticket granting ticket represents the selected identity. As such, obtaining a Kerberos v5 ticket is mandatory.

The Credential lifetime option can control how long the initial ticket will be valid for.

When Forwardable tickets are received from the Kerberos Server, these tickets can be forwarded to a remote host when you connect via telnet, ssh, ftp, rlogin, or similar applications. When tickets are forwarded, there is no need to obtain Kerberos tickets again to access Kerberized services on the remote host. Forwardable tickets are often required when authenticating to a remote host using ssh or ftp when the remote host requires the ability to authenticate to a remote file system such as AFS.

When Renewable tickets are received from the Kerberos Server, the ticket lifetimes may be renewed without prompting the user for her password. This allows Kerberos tickets to be issued with short lifetimes allowing compromised accounts to be disabled on short notice without requiring the user to enter a password every few hours. When combined with Automatic Ticket Renewal, NetIdMgr can maintain valid tickets for a week, a month, or longer by automatically renewing tickets prior to their expiration. The ability to renew tickets without a password is limited by the ticket's renewable lifetime as issued by the Kerberos Server.

When Addressless is selected, the tickets do not contain IP address information. This enables the tickets to be used from behind Network Address Translators which are frequently found in Cable and DSL Modems.

The Credential cache setting controls the location of the Kerberos v5 credentials cache where the obtained credentials will be placed. By default, the Kerberos v5 provider places credentials in an API: (in-memory) cache. However, you can specify any type of cache supported by the Kerberos for Windows. The Browse for FILE: cache button allows you to browse for an existing file or specify the name for a new file which will be used as a FILE: cache. If the file does not exist, it will be created the next time you obtain new credentials for this identity. The cache is also automatically added to the list of FILE: caches that are monitored by Network Identity Manager.

Note:

The Kerberos v5 provider does not check whether an existing FILE: cache is valid when setting the credentials cache for an identity.
