KfW 3.2.2 multiple users via SSH

[petesea@bigfoot.com]

I'm using Kerberos for Windows 3.2.2 on Windows XP SP3 and noticed a 
problem using kinit/klist when multiple users ssh to the host.

If I ssh to the windows host as "userA", then run klist, I see the 
following:

(as userA - krbcc32s NOT running)
   $ klist
   klist.exe: No credentials cache found (ticket cache API:krb5cc)

That's as expected.   And... looking at ProcessExplorer, the krbcc32s 
process is now running as "userA".

Now, ssh as "userB" and run klist:

(as userB - krbcc32s running as userA)
   $ klist
   klist.exe: Credentials cache I/O operation failed XXX while getting default ccache

If I kill krbcc32s and redo the test, but login as "userB" first, I see 
just the reverse, ie:

(as userB - krbcc32s NOT running)
   $ klist
   klist.exe: No credentials cache found (ticket cache API:krb5cc)

(as userA - krbcc32s running as userB)
   $ klist
   klist.exe: Credentials cache I/O operation failed XXX while getting default ccache

My first suspicion was the fact that the CC is the same for both users 
(API:krb5cc), but if I redo the above tests and set KRB5CCNAME to 
something unique for each user (eg. API:krb5cc_userA, API:krb5cc_userB) it 
fails the same way.

If I use a unique "FILE:" credentials cache for each user (eg. 
FILE:C:/tmp/krb5cc_userA, FILE:C:/tmp/krb5cc_userB), then it seems to 
work, but krb5cc32s is running as the first user who started it, which 
bothers me.

Soooo... 2 questions:

   1) Is is not possible to use an API: credentials cache for more then one 
user?

   2) Is it OK to use a FILE: credentials cache in this case even though 
krb5cc32s is running as the first user who started it?
