Are you proposing that the non-Microsoft KDC issues tickets containing PAC data and gets the group membership information from the Active Directory using LDAP ?

Subject: Kerberos Feature Request
I probably should send this to the IETF group, but I'm not on their mailing lists. (Apologies if the cross-posting causes problems.) It would be *nice* if all Kerberos distributions added this feature the same way.
One of the famous things that Microsoft did in their AD Kerberos implementation is added authorization data to the (supposedly
optional) PAC field that is necessary when using certain other Microsoft functionality. AFAIK all of the information added is also contained in the LDAP directory that AD also provides.
I do not think it makes any sense for a (non-Microsoft) Kerberos server to directly maintain this data. Rather it should have a mechanism for acquiring the data from an external source, such as an LDAP directory.
My request is that the Kerberos community agree on a standard external interface to get that data. If the interface itself were standardized then the work of connecting that interface to the appropriate AD attributes could be done independently of any Kerberos server, and could be updated as Microsoft updates their schema independent of Kerberos versions. It would also make the use of PAC data in non-Microsoft environments much easier to consider.
The opinions expressed in this message are mine, not those of Caltech, JPL, NASA, or the US Government.
