Here is some more information. If I enable "showacls" on the Solaris 8
smbclient, it does not segfault but the Size: contains %f and not the
actual size in bytes. On a similar build for Redhat Linux 4, it works
in both cases. Here is the output from this test:

Is there anything else I can do to help track this problem down?
Is anyone else running Samba 3.0.28 on Solaris 8? With Heimdal Kerberos
or with MIT Kerberos? I would appreciate any feedback.
Cheers,
Ken
