The implementation of GSS name attributes for Kerberos (or any mechanism
with more than a tiny handful) is much nicer as a table-driven
implementation.
We now have stubs for setting and deleting attributes as well, though
these currently always fail.
This adds Kerberos mechanism support for:
- composite principal name export/import
- getting rudimentary name attributes from GSS names using
gss_get_name_attribute():
- all (raw) authorization data from the Ticket
- all (raw) authorization data from the Authenticator
- transit path
- realm
- component count
- each component
- gss_inquire_name()
- gss_display_name_ext() (just for the hostbased service name type
though)
The test exercises almost all of the functionality, except for:
- getting the PAC
- getting authz-data from the Authenticator
- getting the transit path
TBD (much) later:
- amend test_context to do minimal name attribute checks as well
- gss_set_name_attribute() (to request authz-data)
- gss_delete_name_attribute()
- getting specific authorization data elements via URN fragments (as
opposed to all of them)
- parsing the PAC, extracting SIDs (each one as a separate value)
- some configurable local policy (?)
- plugin interface for additional local policy
