Making sets of users priveleged

I just imported a bunch of users from ldap and realized after the fact I
forgot to make sure they were imported as privileged users. I’ve been
casting about for a recipe/tool to flip that sets that bit for lots of
people at once and have struck out. Might someone be able to point me in
the right direction?

Thanks for your help,

It may not help you any but what I would like to do is to have rt ask 

ldap for group membership.
