not realy, because i haven't done the installation... , only the upgrade...

have setup "$conf['auth']['admins'] = array('test1 at address.de');""
but no login with the adminuser

is there any way to find out why horde is blocking the login? 
logfiles,debuglevel?

if not, i will reinstall with version 5.0.3
