* when its sign_authdata method is invoked.

* KRB5_KDB_FLAG_CLIENT_REFERRALS_ONLY: Set by the KDC when looking up the

* KRB5_KDB_FLAG_MAP_PRINCIPALS: Set by the KDC when looking up the client
* entry during TGS requests, except for S4U TGS requests and requests
* where the server entry has the KRB5_KDB_NO_AUTH_DATA_REQUIRED
* attribute. Indicates that the module should map foreign principals
* to local principals if it supports doing so.
*
* KRB5_KDB_FLAG_PROTOCOL_TRANSITION: Set by the KDC when looking up the
* client entry during an S4U2Self TGS request. This affects the PAC
* information which should be included when authorization data is
* generated; see the Microsoft S4U specification for details.
*
* KRB5_KDB_FLAG_CONSTRAINED_DELEGATION: Set by the KDC when looking up the

* realm being served.
*
* KRB5_KDB_FLAG_ALIAS_OK: Set by the KDC for server principal lookups and
