public final class ServicePermission extends Permission implements Serializable
A ServicePermission contains a service principal name and a list of actions which specify the context the credential can be used within.
The service principal name is the canonical name of the
KerberosPrincipal supplying the service, that is
the KerberosPrincipal represents a Kerberos service
principal. This name is treated in a case sensitive manner.
An asterisk may appear by itself, to signify any service principal.
Granting this permission implies that the caller can use a cached credential (TGT, service ticket or secret key) within the context designated by the action. In the case of the TGT, granting this permission also implies that the TGT can be obtained by an Authentication Service exchange.
The possible actions are:
initiate - allow the caller to use the credential to initiate a security context with a service principal. accept - allow the caller to use the credential to accept security context as a particular principal.For example, to specify the permission to access to the TGT to initiate a security context the permission is constructed as follows:
To obtain a service ticket to initiate a context with the "host" service the permission is constructed as follows:
For a Kerberized server the action is "accept". For example, the permission necessary to access and use the secret key of the Kerberized "host" service (telnet and the likes) would be constructed as follows:
