Allow diff. users per post

Hi there fellow bloggers,

I’m having a hard time protecting my site. First some background info on the site so you can (hopefully) better help me.

Background info:

It’s a corporate site which should allow clients acces to different pages which are specificly for them.

Problem:

I havent found a single plugin or combination which allows me to:

– Protect posts (not pages) by user-role.

Possible solution:

When I can make a user role, and specify while writing a post, whom might see it, it’d be fixed.

Any help would be appreciated very very very much. Thanks in advance!
