Trex Authorization Issue

Hi All,

We want particular objects to be searched and hence we created the TREX.We created the Index in the System Administration >System Configuration >Index Admininstration.

After creating the Index, when we are about to add the data source for the folder we get the following error message(when we click the ADD button)"Authorization Required"

"The repsoitory you are trying to access requires specific permissions which you did not provide.Make sure you provide the appropriate access information for this repository."

But we logging into portal using administrator and still we get this error.Our Index folder is also in active status only and it does not contain any errors when creating it.

Can you please guide me as what can be the solution for this error and hence we can enable the Trex to work.

Thanks in Advance.

Regards,
