Try comparing the file before and after to see the differences.
Have you checked the logs? Are you getting an error?
As the article talks about changing a number of different files, it's hard to tell. I.e. Your file posted does not contain any of the stuff in the article, like the ^/api firewall
Maybe create the skeleton line for line in the article in a separate folder, then compare with your project, file by file, adding the skeleton stuff...
It seems like you are not telling your main firewall which provider to use for authentication, so your api one could be overriding it...
I.e. Your main: form_login: provider: needs to be users, and your api can use the fos_user bundle
Both should be able to use the same provider for with as long as the field names are the same
Edit:
1) Checkout symphony firewalls and access control
2) Decide whether you want the same users as your main site, or a different user provider for the api
3) Point the form_login in the relevant section of the firewall to the user provider you want to use
Above you have one provider registered, "users" in the provider section.
Assuming you wanted separate users to your main site:
If you followed the article, you would have put "fos_userbundle" as another provider in that section, and added the firewall sections to allow oauth for the api. Under "form_login" on "aouth_authorize" there is a provider that points to the fos_userbundle. You should have also added the api route to control which route your api responds to (pattern: ^/api <== any route starting with api)
I suspect your user provider under the main section now doesn't know which user bundle to use to authenticate. i.e. have you tried to login as an api user on your main site? Does it authenticate? If so, you need to tell your "main" section in the firewall, that the user provider must be the "users" provider by adding provider: users to the "form_login" section of the firewall.
If you want to use a separate user provider for your main site and your api:
