Not hard.

Call user_load($array) where $array is an array that looks like ('name'
=> $name, 'pass' => $pass). If the returend object has an item uid, then
you were successfull.

Look in og.module and call the responsible function. Otherwise you'll
need to query the node_acess table directly.

There are some exapmple script that come with the devel.module in the
generate subdirectory. Those are mainly for inserting stuff, though.
