User Administration Tools

Does anyone have a user administration tool that they like? It seems that there are two common operations that have to be performed:

1. Create a new login for a user, and grant all of the database access rights and role memberships already assigned to another user. In other words, "Make User B just like User A." This same operation has to be performed for multiple servers.

2. Copy a login to a different server. This is usually done to add someone to a test environment. The database names and role names are the same, but the server is different.

In our environment, adding a new employee involves going to three different servers, finding a "model" login, and adding the database access rights for three or four databases, with three or four role memberships in each database. Some databases have thirty or more roles defined, so it's easy to miss a checkmark when scrolling through a list of that size.

I have tinkered with some scripts to do this, but they usually fail because things like sp_addrolemember only work in the current database. I am about to start writing something in VB to do this, but I don't want to reinvent the wheel if someone has already done something similar.
