| * RFC 4120 |
| * |
| * AD-INTENDED-FOR-SERVER SEQUENCE { intended-server[0] SEQUENCE OF |
| * PrincipalName elements[1] AuthorizationData } |
| * |
| * AD elements encapsulated within the intended-for-server element may be |
| * ignored if the application server is not in the list of principal names of |
| * intended servers. Further, a KDC issuing a ticket for an application server |
| * can remove this element if the application server is not in the list of |
| * intended servers. |
| * |
| * Application servers should check for their principal name in the |
| * intended-server field of this element. If their principal name is not found, |
| * this element should be ignored. If found, then the encapsulated elements |
| * should be evaluated in the same manner as if they were present in the top |
| * level authorization data field. Applications and application servers that do |
| * not implement this element should reject tickets that contain authorization |
| * data elements of this type. |
