This can be a tricky problem, as the permissions are not attributes of the
trustee as listed in AD, but of the resources being permitted, for example,
NTFS volumes, printer shares, and exchange mailboxes. The one exception to
this is access permissions to AD itself.

If you are limiting yourself to NTFS volumes, you would need to interrogate
all systems for all available NTFS volumes, and then walk the directory tree
looking for every folder and file to which the user in question had any
access, whether specified directly or through membership in a security
group. It gets complicated and the report voluminous.

There are surprises too. For example, if your script determined that if user
A had access to folder B due to membership in group C, removing the account
from this group might not necessarily remove that access, as A could be a
member of group D, which also has access to B. Therefore you would need to
note each such relationship.

If you wish to run the script from the account you are inquiring about, you
will need to enumerate all shares, hidden and otherwise, as these may point
to folders hidden within folders you do not have access to.

Your best approach will likely depend on the underlying purpose. Whenever I
have had to do something similar it was because I needed to analyze the
permission structure in order to normalize access by, for example, removing
explicit permissions on a per user basis. I mainly used CACLS and examined
the output with an editor and/or filter.
