When i access /cas/login page then CAS works successfully - it's identify user automatically.

But when i access application (cas client https://some-apps.domen.com) then 500 error happens:

https://cas01-test.apps.domen.com/cas/login?service=https%3A%2F%2Fsome-apps.domen.com

Could you please advise how to fix it?
