Using a cache to insert usernames/passwords

I have searched high and low for a solution for the following.

We have access to a database with information used in education here.

We need to enable our students/teachers to access it without telling
everyone the password.

The database used to be accessible via telnet which enabled us to write
a simple daemon to insert username and password in the telnet stream.
But they decided to 'upgrade' to world wide web.

Being on a Lotus Notes Domino server it seems to be impossible to get the
server to recognize our IP block as having access anyway.

Since we use a webproxy anyway with autoproxyconfig, is there a way to
insert the needed username/password in the http stream too ? Did someone
write anything for this ? I'm thinking of a separate simple proxy for this
task.

Thanks in advance for any hint/pointer,
