Hi Valerie
Please review the capaths code change at
http://cr.openjdk.java.net/~weijun/8012615/webrev.01/
It includes:
Config.java
===========
Add method to check if a sub-stanza exists.
Realm.java
==========
Rewrite reading cross-realm path for both [capaths] and hierarchy. The
[capaths] part implements the chaining process.
CredentialsUtils.java
=====================
When reading cross-realm TGT for a path A->B->C->D->SERVERREALM, the
current impl first gets krbtgt/SERVERREALM@A, and then fallback to
krbtgt/D@A, krbtgt/C@A and krbtgt/B@A. In fact, since the capath is
already there, krbtgt/B@A should be the first to check. I don't know
about the history of this code and dare not change much. But I at least
reverse the order of the fallback (what the code calls inner loop) to
try krbtgt/B@A first.
Tried on a local setup of 5 MIT KDC realms configured with a
one-direction cross-auth from K1 to K5. The MIT kvno command starts with
kinit in K1 and goes thru krbtgt/K2@K1, krbtgt/K3@K2, krbtgt/K4@K3,
krbtgt/K5@K4 and finally get service ticket to host/host.k5@K5. Now Java
can do the same with the same krb5.conf.
Thanks
