# Which Problems Are Solved
* v2 login ui was ignoring oicd `ui_locales` making it impossible to
sync the login ui locale with the apps ui
# How the Problems Are Solved
- Read `uiLocales` from `authRequest`
- check all listed if valid in ui
- take the first valid one
- set language cookie (if a valid locale is pressent in uiLocales)
# Additional Changes
- tests
