Ok, the question still holds: application calls krb5_sname_to_principal()
with hostname == NULL which internally uses getaddrinfo() to determine the
canonical local hostname. On AIX, it results in a principal name of the
form "host/hostname@REALM", whereas the keytab contains "host/FQDN@REALM".
So the application can not find the correct keys and authentication fails.
Is my first idea (try to fix the value returned by getaddrinfo() to always
include the domain part; using getnameinfo() is a good candidate to do that)
should be followed, or the problem should be handled a different way?
