ADFS 2.0 + Picking up random values from multi valued attribute

Hi,

I am writting a custom rule in ADFS 2.0 This claim shall fetch an Active directory multi-valued attribute. Further I have to retrieve all the values (of the fetched attribute) one by one and perform a search on them to see who is the memberOF the application group.

I am not able to find any pointer in achieving this, can anyone please help me to resolve this issue?

Thanks,

Murtuza Kolsawala.
