Package: libapache2-mod-auth-kerb
Version: 5.4-2.2
Severity: normal

Let's assume the following sample VirtualHost configuration.

<VirtualHost *:80>
        ServerName testwww.foo.bar

        ServerAdmin webmaster@localhost
        DocumentRoot /home/apache/http_root/testwww/public

        <Directory /home/apache/http_root/testwww>
          AuthType Kerberos
          AuthName "Please login to proceed"
          KrbAuthRealms FOO.BAR
          KrbServiceName HTTP
          Krb5Keytab /etc/apache2/apache.keytab
          KrbMethodNegotiate on
          KrbMethodK5Passwd on
          KrbLocalUserMapping On
          Require valid-user
        </Directory>
</VirtualHost>

When web browser uses "negotiate" authentication method, everything
works fine. But when apache tries to perform "K5Passwd" method via
acquiring plain login and password from user, the auth_kerb module reads
incorrect keytab.

It should use "Krb5Keytab" file defined in config. In my example it is
"/etc/apache2/apache.keytab". But in fact the module reads the system
default keytab instead. Usually it is placed in "/etc/krb5.keytab".

So, mod_auth_kerb ignores the directive "Krb5Keytab" while checking
against plain login and password, provided by user. Thus, in the case
when apache configured keytab differs from the system default keytab,
the same user on the same machine in the same time successfully signs in
via SPNEGO and fails to authenticate via login and password. I beleive
this is a bug.
