Login problem when deploying Jetspeed

[Tommi Lukkarinen]

Hi, I could not login as Admin after deploying Jetspeed, login with a/a returns correctly invalid username: login with admin/a returns correctly invalid password: login with admin/admin does not return any error, but the client stays in unlogged state and fields in the form are cleared, no clue in logs: Do you have any clue what could be the cause, I followed deployment guide.
