Requirements to reproduce the issue:
- GitHub account
- OpenShift Cluster

Steps to Reproduce:
1. Create a private repository on GitHub
2. Create a GitHub personal access token [1]
3. Create `kubernetes.io/basic-auth` secret
   ~~~
   $ oc create secret generic user-at-github --from-literal=username=<github_username> --from-literal=password=<github_token> --type=kubernetes.io/basic-auth
   ~~~
4. Link secret to builder ServiceAccount
   ~~~
   $ oc secrets link builder user-at-github --for=pull,mount
   ~~~
5. Create a new app from the private GH repo

Argument 'https://github.com/gmeghnag/prinquest' was classified as an image, image~source, or loaded template reference.

The 'oc new-app' command will match arguments to the following types:

  1. Images tagged into image streams in the current project or the 'openshift' project
     - if you don't specify a tag, we'll add ':latest'
  2. Images in the Docker Hub, on remote registries, or on the local Docker engine
  3. Templates in the current project or the 'openshift' project
  4. Git repository URLs or local paths that point to Git repositories

--allow-missing-images can be used to point to an image that does not exist yet.

See 'oc new-app -h' for examples.

Expected results:

To have all the required resources created (build, buildconfig, ecc..)

Additional info:
1. I have the same issue trying to create a new app from the OpenShift Console (Developer Console > Add + > Import from Git > ...) with the following error:
   ~~~   
   URL is valid but cannot be reached. If this is a private repository, enter a source Secret in advanced Git options
   ~~~

2. Is not an issue related to the creds I've provided:
   ~~~
   $ GH_USERNAME=$(oc get secret/user-at-github -o template='{{index .data.username}}' | base64 -d )
   $ GH_PASSWORD=$(oc get secret/user-at-github -o template='{{index .data.password}}' | base64 -d )
   $ git clone https://${GH_USERNAME}:${GH_PASSWORD}@github.com/gmeghnag/prinquest.git
   Clone in 'prinquest' in corso...

3. Using `ssh-auth` instead of `basic-auth` as authentication method works:
   3.1 ssh-keygen -f git-cred -N ''
   3.2 oc create secret generic git-cred --type=kubernetes.io/ssh-auth --from-file=ssh-privatekey=${PWD}/git-cred.pub
   3.3 oc secrets link builder git-cred
   3.4 from GitHub repository > Settings > Deploy Keys > Add Deploy Key (paste the content of the file git-cred.pub)
   3.5 oc new-app git:<username>/<repo_name>.git --source-secret git-cred
