Constant automatic logout in Information Design Tool

My Client has a BusinessObjects BI 4.0 SP5 with oracle 11g for repository.

The tool that i am working is Information design tool and I was trying to log into a session.

However the system continuously logged me out from the session after a few second.

Here are my findings:

- if I login as user with administrative privileges, I will not be automatically logged out.

- if I login as user without administrative privileges, I will be automatically logged out after few second.

Does anybody know of this issue? A solution would be wonderful 😊
