Facing issue while configuring Kerberos SSO

Hi All,

I am facing an issue while configuring Kerberos SSO in Peoplesoft. Tools : 8.52.06 and App : FSCM 9.1

I have done the configuration and thing are going fine till webserver, I mean, I saw the webserver logs and found that I am getting the valid token and then it send it for mutual authentication but when it goes to Appservers as per the log, It loads all the class and classes jar files and gives me the issue as PUBUSER (Public User) does not have any roles, You can add Roles with the --Maintain Security > Use > User Profile-- pages, Authorization Error -- Contact your Security Administrator.
