Limiting members to an external database

There are also some hacks around (search for them) limiting the mail addresses used to signup to 1 domain for example, or other limitations to the signup process.

Hi there.

I'm looking at about 1200 members, and they should all be joining in the first month or two. So this is a bit of an issue.

What I have done is added a User Profile Field called ID number.

Is there any way that I could have a script in between the register page and the complete registration script, where I can check the ID field against the database of users? If there is no matching ID number in the DB, the user gets sent back to the registration page informing him of the problem.

I'm sorry I'm so dense on this subject, but I don't even know where to start. I can write the intermediate script, but have no idea how to incorporate it in the whole process. Especially the informing him of the problem part.

Thanks a lot for your help.
