Motivation
- get rid of the insecure basic authentication of opendaylight for Restconf
- instead implement JsonWebToken(JWT)
Problems
- Opendaylight AAA project for aluminium-SR1 is only supporting authorization header starting with "Basic" and JWT is a Bearer token
- So we had to patch the org.opendaylight.aaa:aaa-shiro:0.12.1 bundle with
- some backported classes from org.apache.shiro:shiro-core:1.7 package
- two modifications on the Authenticator to Accept also Bearer tokens
- we realized that an entry in aaa-app-config.xml like
<urls>
<pair-key>/**</pair-key>
<pair-value>authcBasic, roles["admin,provision"]</pair-value>
</urls>
means that the user which wants to access this url pattern needs to have both roles, which does not really make sense. Therefor we also implemented a so called AnyRolesAuthenticationFilter which accepts the connection if one of the given roles matches.
