The following example allows any user to perform any action (GET, POST, etc.) on /login. This is just one way to do it. You can also make * as a special role that every user has, or hack a new role manager to allow the use of *. Or you can hard-code /login, /logoff, /signup into the matcher or in a custom function.

Model:

[request_definition]
r = sub, obj, act

[policy_definition]
p = sub, obj, act

[role_definition]
g = _, _

[policy_effect]
e = some(where (p.eft == allow))

[matchers]
m = (g(r.sub, p.sub) || p.sub == "*") && keyMatch(r.obj, p.obj) && (r.act == p.act || p.act == "*")

Policy:

p, *, /login, *

Can you try to run this test: https://github.com/gin-contrib/authz/blob/master/authz_test.go ? The test actually uses the authz middleware and can get correct result (200 or 403).
