1. configure authorization server spring-security-oauth. necessary endpoints mapped automatically (including /oauth/token)
2. make simple webpage login form
3. make post request /oauth/token username , password. in addition have send field called grant_type filled 'password' value.
   4. as response receive access token. means authenticated.

p.s. please pay attention oauth authorization standard, not authentication one!
