Apache and Kerberos SSO issues


I am trying to set up a linux server running apache2 and mod_auth_kerb to authenticate users against our Windows 2003 AD server.

I have got the server to authenticate with AD using kerberos, however this is only possible with the authentication dialog box appearing. I can't seem to have the users authenticate seamlessly i.e. without the dialog box.

I would prefer to use krb rather than LDAP as we have users in different OUs for each business group.

Here is the contents of the .htaccess file

AuthName "Intranet"
AuthType Kerberos
Krb5Keytab /usr/lib/krb5/auth_kerb.keytab
KrbMethodNegotiate off
KrbSaveCredentials off
KrbVerifyKDC off
Require valid-user
Any ideas how I can get users to authenticate against the server without the dialog box?

You have set
KrbMethodNegotiate off
which actually is the "without dialog box" option.

Recommend using
KrbMethodNegotiate On
KrbMethodK5Passwd Off
This disables the dialog box, and enables only the GSSAPI authentication.

I really recommended using
LogLevel Debug
ErrorLog /var/log/apache2/error.log
in your httpd.conf/apache2.conf/virtual hosts file, and check your apache error logs, while trying to authenticate without the dialog box.
