- temporarily bundling the krb5-appl package (split upstream as of 1.8)
until its package review is complete
- profile.d scriptlets are now only needed by -workstation-clients
- adjust paths in init scripts
- drop upstreamed fix for KDC denial of service (CVE-2010-0283)
- drop patch to check the user's password correctly using crypt(), which
isn't a code path we hit when we're using PAM

Reference docs don't define what happens if you call krb5_realm_compare() with
|
|
malformed krb5_principal structures. Define a behavior which keeps it from
|
|
crashing if applications don't check ahead of time.
