When we try to fix or edit klocwork analysis issue from in login jenkins dashboard, we have faced authentication failed error. Usernameltoken file created in jenkins workspace and also jenkins log demonstrate "Klocwork Server could not be read or is empty". When we check usernameltoken file in workspace, it has not permission right for other user. I tried to change token file permission with umask and setfcal but when created new token file again occured same old permission. 

Could not authenticate user betul.aslan. Token returned by Klocwork Server could not be read or is empty
