250  policy, e.g. authentication and authorization credentials presented or used
251  by the peer entity (usually the client of the request), connection state
252  information.
253 
254  The context consists of:
255 
256  1) Identity
257 
258  Verified authentication information, such as principal name for a
259  particular security mechanism.
260 
261  2) Authorized credentials
262  This type of credentials is used to hold delegated credentials and
263  capabilities.
264 
265  3) Group membership
266  This type of credentials specifies that the grantee is a member of
267  only the listed groups.
268 
269  4) Group non-membership
270  This type of credentials specifies that the grantee is NOT a member
271  of the listed groups.
272 
273  5) Attributes
274  This type of credentials contains miscellaneous attributes
275  attached to the grantee, e.g. age of the grantee, grantee's security
276  clearance.
277 
278  6) Unevaluated Credentials
279  Evaluation of the acquired credentials can be deferred till the
280  credential is needed to perform the operation.
281 
282  7) Evaluation and Retrieval Functions for Upcalls
283  These functions are called to evaluate application-specific conditions,
284  to request additional credentials and verify them.
285  The GSS API is an example of how this can be filled in.
286 
287  8) Connection State Information
288  Contains a mechanism-specific representation of per-connection
289  context, some of the data stored here include keyblocks, addresses. */
