SAML SSO Integration

After the integration,I am able to log in with my idp but i am always redirected to this page
Imgur

I retrieved this from the logs
,“user”:"–",“app”:“index”,“method”:“GET”,“url”:"/oc-shib/index.php/login",“message”:"Exception: {“Exception”:“OutOfBoundsException”,“Message”:"Failed to login because no uid (login) was provided

I have integrated owncloud with LDAP
