User not able to login for the role

Hello All

We are having 2 properties for the role assigned to user in portal. One is the "Entry Point" and the second one is "Invisible in Navigation Areas". We have customized the standard TLN par for our application. Due to which if we are setting any of the above property to "Yes" then i am not able to login into that role. As we are checking the navigation nodes only in TLN par.

I need that role to be invisble in portal but user should be able to login into that role.

Kindly help as i need to implement it urgently.

Thanks & Regards

Mandeep
