Max,
The new ordering for reading the config files sounds reasonable.
However, I have questions on scenarios where the various config files
don't exist and the corresponding handling.
The new impl of getJavaFileName()/getNativeFileName() return file names
even when the file doesn't exist.
This will lead to an IOException when loadConfigFile(String) is called.
Is this intended?
Also, the toStringIndented(...) method removed several calls which
append the 'prefix' and made various adjustments.
Do you have sample output using the new impl? Reading through the code,
some don't look quite right.
Thanks,
Valerie

7184815: [macosx] Need to read Kerberos config in files
Please take a review:
http://cr.openjdk.java.net/~weijun/7184815/webrev.00/
I break the config setting to Java setting and native setting, and
insert the reading of SCDynamicStoreConfig between the two. This should
preserve the 6u behavior and add a fallback to legacy config files.
No new regression test, because of SCDynamicStoreConfig and system
config files, will ask SQE to create a manual test.
Thanks

I'm not familiar with how Mac does it, but normally there are two
ways a
Kerberos authentication is performed, through the initial login and
through kinit. The former is integrated into the system (a pam module?)
and I guess in this case the config is inside SCDynamicStoreConfig. For
the latter, the Kerberos clients are regarded as standalone tools and a
/etc/krb5.conf is needed.
Java works in both ways, if there is already a credentials cache it
will
happily use it. On the other hand, it also includes the Krb5LoginModule
that does all the login itself. Therefore, it should read both
styles of
config on a Mac.
I've filed a new bug, It will appear soon at
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7184815
Thanks

Hi Scott
On Mac since Lion, sun.security.krb5.Config tries to locate the
config
info in this order:
1. java.security.krb5.conf system property
2. ${jre}/lib/security/krb5.conf
3. SCDynamicStoreConfig
The main difference from other platforms is that it will not try
config
files, say, /Library/Preferences/edu.mit.Kerberos or /etc/krb5.conf.
On the other hand, even /usr/bin/kinit comes with Lion reads the
config
file (if there is no SCDynamicStoreConfig setting).
Is there a special reason for the current Java behavior? I do notice
that the Apple 6u33 already does this.
No special reason I can think of, beyond simply swapping the
implementation to read from the SCDynamicStoreConfig. Java SE 6 had
previously had been relying on the system to write out a
/Library/Preferences/edu.mit.Kerberos file, but that went away with OS
X 10.7, so we didn't see much point in reading the file, since little
else on the system would be paying attention to it either for the
purposes of SSO.
It seems perfectly reasonable that if there are no
SCDynamicStoreConfig entries, falling back to reading the legacy
config files may be a valid option. I'm actually somewhat surprised
that they are consulted by kinit.
