Apple Mac OS X Server's Open Directory KDC issues MS PAC like
authorization data that lacks a server checksum. If this checksum is
missing, mark the PAC as unverfied, but allow
krb5int_authdata_verify() to succeed. Filter out the unverified PAC
in subsequent calls to krb5_authdata_get_attribute(). Add trace
points to indicate where this behavior occurs.
Thanks to Helmut Grohne for help with analysis. This bug is also
Debian Bug #604925:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=604925
This change should also get backported to krb5-1.8.x.
