DIS Access right(roles and autorizations of DIS)

Hello friends,

I have urgent problem regarding access rights of DIS(Document info. system)

I would like to know the access rights of DIS( Document management system).

for example:

1) For creation of DIS what accesss rights exist and for attaching a file what access rights exist

Where can i find these roles and autorization.

Note: I am looking for the entire autoriazaions and roles of DIS ,not for a particular user.

Rewrad with full points.

Regards
