Right this may get very hard to describe, but please try to understand my problem.

I have an apache server set up on my computer and i have a directory one under the root directory called 'admins'. What i want is a .Htaccess file that would deny access to this file by user name. (not i.p because some users log on form the localhost.).

At the moment all i have is:
Require user admin

This works, but this way prompts an already logged in user for another username and password. What i would like is for them to just receive the 'forbidden' page unless their username is 'admin'.
If any one could help (or understand this problem) please reply, or direct me to a place where i may be able to find my required answer.
Thanks
Love Sythe
