- These examples have the following prerequisites:
- * Hashicorp Vagrant
- * VirtualBox
- The test environment relies upon a host only network configured within VirtualBox with a CIDR range of 10.80.0.0/16
- If this does not suit your setup then you will need to set the IP addresses for the private_network in the Vagrantfiles to something that suits you.
- You will also need to update the IPs referenced in the testdata/test_vectors.go file in the TEST_KRB5CONF constant.
- Before running execute the following commands (note that the KDC can take a long time to start up):
- cd $GOPATH/src/github.com/jcmturner/gokrb5/testenv/krb5kdc-vagrant && vagrant up
- cd $GOPATH/src/github.com/jcmturner/gokrb5/testenv/krbhttp-vagrant && vagrant up
