THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

- Copy the Keroes keytab file
krb5.keytab
to one of directories of your Geronimo Server. The file was created during Setting up the Domain Controller Machine. - Create a basic Kerbeores configuration file named
krb5.ini
in order to use the SPNEGO for the server. The files should be stored on local server and with the following keys list defining the Kerberoes key distribution center(KDC) name and the realm setting for the SPNEGO authentication.Code Block title krb5.ini [libdefaults] default_realm = XYZ.COM default_keytab_name = FILE:c:\winnt\krb5.keytab default_tkt_enctypes = rc4-hmac,des-cbc-md4,des-cbc-crc default_tgs_enctypes = rc4-hmac,des-cbc-md4,des-cbc-crc forwardable=true [realms] XYZ.COM = { kdc = domaincontroller.xyz.com:88 default_domain = xyz.com } [domain_realm] xyz.com= XYZ.COM .xyz.com = XYZ.COM
- Configure JVM properties with the following key pairs to make sure the JVM read the Kerberoes configurations successfully.
Panel boderstyle solid set JAVA_OPTS=-Djava.security.krb5.conf=C:\winnt\krb5.ini -Dcom.ibm.security.jgss.debug=all -Dcom.ibm.security.krb5.Krb5Debug=all -Djavax.security.auth.useSubjectCredsOnly=false
- Create a system-scope realm for the Geronimo server as followed. The sample code is a combination of SPNEGO and .properties file realms in order that the authentication will fall back on .Properties realm once the SPNEGO authentication fails. You can remove the .properties file realm if unnecessary.

- Configure the deployment plan of your application to make sure the SPNEGO realm is invoked properly. See the sample code below for reference.

- Configure the deployment descriptor to make sure your application uses SPNEGO authentication and the respective realm provider that Geronimo server supports.
