When using the openid plugin, it is not possible to configure the instant-messaging plugin to authenticate using the apitoken as password. It's not clear from the error if the problem is the password or some compatibility between both plugins.

The following message is shown in the jenkins log:

WARNING: IRC notifier plugin couldn't authenticate against Hudson: org.acegisecurity.BadCredentialsException: Unexpected authentication type: org.acegisecurity.providers.UsernamePasswordAuthenticationToken@cf61c327: Username: hal; Password: [PROTECTED]; Authenticated: false; Details: null; Not granted any authorities
