Unable to connect REST URL of PI system with j_username and j_password as parameter query

Hi Experts,

I am trying to connect REST URL of PI system from SOAPUI. When I pass basic authentication its working.

But while passing j_username and j_password as parameter query its throwing 401 - Not Authorized. I even check ume configuration and its configured as "ume.logon.userpwd_automatic_logon = true".

Is there any other configuration need to check ?

Thanks,

Bijaya
